First WIP commit, adds:
- enum GimpGradientBlendColorSpace { RGB_PERCEPTUAL, RGB_LINEAR }
- linear blending mode for gradient segments
- tool options GUI for the blend and paint tools which use gradients
Replace the "lock brush size to zoom" paint option with a "lock
brush to view" option, which links the entire brush transform to
the view transform, so that the brush remains invariant in display
space under scaling, rotation, and reflection.
...are not submitted to respective Tool Options sliders
Treat brush angle and aspect ratio like all other paint options values
that can be linked to brush defaults and take their default values
from the brush. They were special casing their defaults to constants,
and GimpBrushGenerated was adding the passed dynamic radius and aspect
values to its own. This was totally incomprehensible.
Now GimpBrushGenerated's transform_size() and transform_mask()
implementations just translate between these APIs value ranges and the
brush's own value range and only use the passed values (not the
brush's native values), which makes the editor <-> tool options
interaction and the painted brush shape predictable.
Also connect the active brush's property notifications to the paint
options properties, so the paint options follow a brush edit live if
the respective "linked" toggles are checked.
And some cleanup.
Add "link" buttons to the tool options that are duplicates of brush
properties, so the tool options values can be set to change along with
the current brush.
and use it globally instead of two different methods, one of which was
forgotten to be ported to the new aspect ratio range where 0.0 means
1:1. Add a FIXME comment in paint_tools.pdb where I think setting the
default size is a bug, see #721249.
because it belongs to the gradient and should be changed whenever the
gradient gets changed.
Introduce gimp_paint_options_copy_gradient_props() and call it at the
right places in the tool manager.
Rebased/fixed to go on top of current master. Next commit will add cleanup.
Had to change author tag because gnome is not accepting random stuff
in email fields. Original author is tarai, from gimp painter project
in sourceforge.

Bug 520078 – Rotate brushes
Applied a slightly modified patch from Alexia Death:
* app/core/core-types.h (struct GimpCoords): add "direction" member.
* app/core/gimpcoords.c: take direction into account in mix(),
scalarprod(), length_squared(), manhattan_dist() and equal().
* app/core/gimpcoords-interpolate.c
(gimp_coords_interpolate_catmull): same here.
* app/display/gimpdisplayshell-coords.c
(gimp_display_shell_eval_event): same here.
* app/paint/gimppaintoptions.[ch]: add properties for direction
dynamics and adapt dynamics mixing accordingly.
* app/paint/gimpbrushcore.c (gimp_brush_core_interpolate):
"interpolate" direction too (in fact, just copy it from
last_coords since it doesn't change along a straight line).
* app/paint/gimppaintcore-stroke.c
(gimp_paint_core_stroke_emulate_dynamics): emulate direction too.
* app/tools/gimppaintoptions-gui.c: add GUI for direction dynamics.

Bug 520078 – Rotate brushes
Applied patch from Alexia Death:
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.c
* app/core/gimpbrush-transform.[ch]: affine transformations for
brushes. So far only scaling and rotation is supported. The
transformation is done using nearest-neighbour. This is a
regression and we need to add back interpolation before the next
release.
* app/paint/gimpsmudge.c
* app/paint/gimppaintoptions.[ch]
* app/paint/gimpbrushcore.[ch]: allow to control the brush
rotation angle.
* app/tools/gimppaintoptions-gui.c
* app/tools/gimpbrushtool.c: added UI for controlling the
brush rotation angle.
* app/actions/tools-actions.c
* app/actions/tools-commands.[ch]: add actions for controlling
the
brush rotation angle.

2008-05-26 Michael Natterer <mitch@gimp.org>
Applied modified patch from Alexia Death. Addresses bug #534770:
* app/paint/gimppaintoptions.[ch]: add properties for scaling
the effects of pressure, velocity and hardness and honor them
in the various get_dynamic_foo() functions.
(gimp_paint_options_get_dynamic_size): look at
pressure_options->size again, that code got lost in one of the
earlier patches.
* app/tools/gimppaintoptions-gui.c: add GimpScaleButtons to the
table for the new properties.
* app/display/gimpdisplayshell-coords.c: don't let "velocity"
reach 1.0, use 0.9999 instead.
svn path=/trunk/; revision=25816
2008-05-26 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintoptions.[ch]: replace the identical
GimpPressureOptions, GimpVelocityOptions and GimpRandomOptions
struct by a single GimpDynamicOptions struct.
* app/tools/gimppaintoptions-gui.c: don't pass the various
sub-structs to the _options_gui() function because they are not
needed.

2008-05-22 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintoptions.[ch]: replace the pressure-expanded,
velocity-expanded and random-expanded properties by a single
dynamics-expanded property.
* app/tools/gimppaintoptions-gui.c: pack the toggle matrix into an
expander, some cleanup.

2008-05-22 Michael Natterer <mitch@gimp.org>
Applied slightly modified and fixed patch from Alexia Death which
adds a "random" axis to the paint dynamics and fixes some issues
in the previous paint dynamics commits. Fixes bug #529431.
* app/core/core-types.h: add a "random" axis to GimpCoords.
* app/display/gimpdisplayshell-coords.c: set it to a random value.
* app/display/gimpdisplayshell-callbacks.c: on button_press,
use the dynamics from the last motion event to avoid blotches
at the beginning of paint strokes.
* app/paint/gimppaintoptions.[ch]: add random properties the same
way we do pressure and velocity. Add get_dynamic_size(),
get_dynamic_color() and get_dynamic_hardness() functions which
look at all dynamic parameters of the passed coords.
* app/tools/gimppaintoptions-gui.c: add gui for the random options.
* app/paint/gimpbrushcore.[ch]: remove calc_brush_scale() and use
gimp_paint_options_get_dynamic_size_instead().
Add "dynamic_hardness" parameters to paste_canvas(),
replace_canvas() and get_brush_mask().

2008-05-10 Michael Natterer <mitch@gimp.org>
Applied modified patch from Alexia Death which adds velocity
support to paint tools in the spirit of the pressure support we
already have. Fixes bug #529431.
* app/display/gimpdisplayshell-coords.c
(gimp_display_shell_eval_event): tweak velocity calculation to
work in screen coordinates.
* app/paint/gimppaintoptions.[ch]: add velocity options in the
same way as there are pressure options. Add utility functions
which return dynamic opatity and dynamic rate according to the the
option's settings and some GimpCoords' pressure and velocity.
* app/tools/gimppaintoptions-gui.c: add GUI for the velocity
options.
* app/paint/gimpbrushcore.h: remove PRESSURE_SCALE define, it's
now in gimppaintoptions.h.
* app/paint/gimpbrushcore.c (gimp_brush_core_interpolate):
inerpolate velocity too.
(gimp_brush_core_calc_brush_scale): take velocity into account.
(gimp_brush_core_get_brush_mask): always pressurize the mask in
the GIMP_BRUSH_PRESSURE because there always is velocity (unlike
pressure which is only there on tablets).

calculating the gradient color offset.
* app/paint/gimpairbrush.c: do some additional fiddling with
velocity in the asynchronous airbrush timeout.

2006-11-16 Michael Natterer <mitch@gimp.org>
Made all brushes scalable from the tool options. So far only
downscaling is supported since we lack an algorithm for bitmap
brush upscaling. Addresses bug #65030.
* app/paint/gimppaintoptions.[ch]: added "brush-scale" property.
* app/paint/gimpbrushcore.[ch]: separate pressure logic from brush
scaling logic and take paint_options->brush_scale into account.
Added gimp_brush_core_create_bound_segs() which returns BoundSegs
of the correctly scaled brush mask for the brush preview on the
canvas.
* app/tools/gimpbrushtool.c: use gimp_brush_core_create_bound_segs()
instead of doing this here (also removes all knowledge about lowlevel
stuff from this file). Connect to notify::brush-scale of the
paint options and invalidate the brush core's brush accordingly.
* app/tools/gimppaintoptions-gui.c: added brush scale slider.
2006-01-14 Michael Natterer <mitch@gimp.org>
* app/config/gimpconfig-utils.[ch] (gimp_config_connect_full):
variant of gimp_config_connect() which allows the connected
objects to have different propertynames.
* app/widgets/widgets-enums.[ch]: removed enum GimpViewType...
* app/core/core-enums.[ch]: ...and added it here.
* app/widgets/gimpviewablebutton.[ch] (gimp_viewable_button_new):
added "button_preview_size" parameter so the button and popup
preview sizes can be specified separately.
* app/widgets/gimptemplateeditor.c: changed accordingly.
* app/widgets/gimpviewablebox.[ch] (gimp_prop_*_box_new):
new functions which take additional "view_type_prop" and
"view_size_prop" parameters and sync the passed context's
properties with the resp. properties of the viewable button.
* app/paint/gimppaintoptions.[ch]
* app/tools/gimpbucketfilloptions.c
* app/tools/gimpclonetool.c
* app/tools/gimppaintoptions-gui.c
* app/tools/gimptextoptions.[ch]: added view-type and view-size
properties to the options objects and use the new viewable box
constructors so the selected view types and sizes are persistant
across sessions. Fixes bug #315443.
* gimp/app/paint/gimpbrushcore.c
* gimp/app/paint/gimpbrushcore.h
* gimp/app/paint/gimpclone.c

* gimp/app/paint/gimppaintoptions.c
* gimp/app/paint/gimppaintoptions.h
* gimp/app/tools/gimppaintoptions-gui.c: Apply patch from
Adrian Likins to add "jitter" to paint tools (bug #163049),
with small fixes for coding style and default jitter set
to 0.2 instead of 0.0.
2005-01-22 Sven Neumann <sven@gimp.org>
* app/widgets/gimppropwidgets.[ch]: added gimp_prop_expander_new().
* app/paint/gimppaintoptions.[ch]: added a property to track the
state of the "Pressure sensitivity" expander.
* app/tools/gimppaintoptions-gui.c: use gimp_prop_expander_new()
to create the "Pressure sensitivity" expander.
2005-01-03 Michael Natterer <mitch@gimp.org>
* app/paint/gimpbrushcore.c
* app/paint/gimppaintoptions.[ch]
* app/tools/gimppaintoptions-gui.c: renamed "invsize" to
"inverse-size" and reordered it to be after "size".
* app/paint/gimpbrushcore.c
* app/paint/gimppaintoptions.c
* app/paint/gimppaintoptions.h
* app/tools/gimppaintoptions-gui.c: reverted last change, and
applied full patch from Dave Ahlswede in bug #149576.
2004-08-31 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintoptions.[ch]: added "GimpPaintInfo *paint_info"
member and construct property. Changed gimp_paint_options_new()
to take only a GimpPaintInfo parameter.
* app/core/gimpitem.c (gimp_item_stroke)
* app/core/gimppaintinfo.c (gimp_paint_info_new): changed accordingly.
* app/core/gimpchannel.c (gimp_channel_stroke)
* app/vectors/gimpvectors.c (gimp_vectors_stroke): use
paint_options->paint_info->paint_type directly instead of casting
to GimpToolOptions and using
tool_options->tool_info->paint_info->paint_type (eek). Fixes crash
when stroking via the PDB because newly created GimpToolOptions
instances have no "tool_info" pointer yet.
* tools/pdbgen/pdb/paint_tools.pdb: changed all paint PDB wrappers
accordingly.
* app/pdb/paint_tools_cmds.c: regenerated.
