In the various types of fill operations, and in fade operations,
use the paint composite-mode of the current paint mode, which is
the composite mode we use during painting, instead of AUTO, which
results in the default mode we use for layer compositing. This
effectively means that filling using any non-legacy, non-
subtractive mode can paint over transparent areas, rather than
being limited to nontransparent areas.
Invalidate the gradient cache while setting relevant properties,
and validate it, reconstructing if necessary, during prepare(),
rather than process(), to avoid the need to use a mutex.
Make sure the cache has at least two elements, corresponding to
the initial and final colors of the gradient, since both colors
might be needed, and to avoid division by zero.
Avoid using a cache if its necessary size is too big, or if the
gradient type is conical, since the necessary cache size for
conical gradients is unrelated to the gradient line length.
Improve index rounding during cache lookup.
Lots of indentation fixes.
When merging a pass-through group, change its mode to NORMAL first,
to avoid a critical when duplicating the group as a regular layer.
Preserve the group's blend/composite space/mode while changing its
mode (note that only the composite space currently matters, since
the other parmaeters are immutable for pass-through groups.)
I could not find for sure what to use on FreeBSD instead, so let's just
not get this information there. It is quite useful information to know
where thread traces were asked from, but it is more important to make
sure the program can be compiled everywhere. Also we can just check
which thread has gimp_stack_trace*() calls. Thus it can be seen as
redundant information in any case.
SYS_gettid is apparently defined as a macro, so let's simply check for
it being defined.

In gimp_text_tool_connect(), when auto-removing empty text layers upon
text layer or tool change, make sure we don't try to remove a layer
that has already been removed, which can happen if this function is
reached *because* somehow the layer was removed externally (e.g. by
the user in the layers dialog).
Things are getting serious now. We need a reasonnable splash, right?
Just in case we have a RC3!
It follows all rules: full HD and bottom fourth empty for loading text.
We were only able to translate selections and layers (bot not channels
and paths) via the PDB, this new procedure fixes that. Deprecation of
old API and some more transform consistency to follow...
it used to be "text" which is almost always too extreme; use "text_aa"
instead which is half way between "text" and "base" and always gives a
reasonable contrast.
... it doesn't exist.
The tmp/ dir in the config folder should already be created by GIMP, but
just in case it is not there, try and create it, since all code calling
these assumes that it exists.
... raises a CRITICAL
gimp_item_{start,end}_move() currently serves two different
purposes: It is used by GimpLayer to suspend/resume mask resizing
of the layer's ancestors; this is necessary whenever an operation
on a layer might affect the size of its ancestors. It is also used
by GimpGroupLayer to suspend/resume its own mask resizing; this, on
the other hand, is only necessary before applying one of the
transformation functions to the group, so that mask modification is
handled by GimpLayer. In other words, the effects of
gimp_item_{start,end}_move() on group layers are only necessary in
a subset of the cases in which these functions are used.
While in itself this isn't a problem, it does cause issues when
removing a group layer: gimp_image_remove_layer() calls
gimp_item_start_move() before removing the layer, and
gimp_item_end_move() afterwards. While the former function is
called while the layer is still attached to the image, the latter
function is called after the layer is no longer attached. Since
GimpGroupLayer pushes an undo step in response to these calls, only
the call to start_move() results in an undo step, while the call to
end_move() doesn't, resulting in an unbalanced
GIMP_UNDO_GROUP_LAYER_START_MOVE undo step on the stack. This
causes problems when undoing the operation.
Add gimp_item_{start,end}_transform() functions, and corresponding
GimpItem::{start,end}_transform() virtual functions, which are more
specialized versions of gimp_item_{start,end}_move(), which should
be used instead of the former before/after transforming an item; in
other cases, such as when removing ot reordering an item,
gimp_item_{start,end}_move() should still be used. The default
implementation of GimpItem::{start,end}_transform() calls
gimp_item_{start,end}_move(), respectively, so subclasses that
override these functions don't have to do that themselves.
In GimpGroupLayer, override GimpItem::{start,end}_transform(),
instead of GimpItem::{start,end}_move(), for the same purpose of
suspending mask resize. This avoids these functions from being
called when removing a layer group, fixing the bug.
In gimp_image_reorder_item(), call gimp_item_start/end_move()
before/after reordering the item (and use an undo group, so that
the resulting undo actions are grouped together with the reordering
undo action,) so that if the item is a child of a group layer, and
reordering moves it out of the group in a way that causes the
group's mask to be resized, the mask will be properly restored when
undoing the operation.
After Alexandre Prokoudine's insistent demand! :-)
I am still not sure how wise this is, since this should be really
considered a "developer-only" option. Basically these tools are really
too buggy and unstable and we should not shine too much light on these.
The counter-argument is that doing so will favor the bitrot.
Well ok. At least let's add a big warning message at the top of the
Playground page, to make it very clear (if that were not already the
case) that basically this is not to be considered a secret feature, but
really more a "we are looking for contributors" option.
In the gimp-channel-combine-masks PDB wrapper, only push an undo step
if the modified channel is attached to an image. It's a completely
reasonable use case to combine unattached channels.
