- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will
paint_core->start_coords is in fact the last stroke's endpoint and
only used for storing it in GimpPaintCoreUndo, so the last endpoint
can be resotred for straight-line painting after an undo. Make the
code actually doing that.
Adjust over-relaxation factor as a function of problem size. Remove
the second array, and update in-place. Factor branches and indexing
out of the inner loop, instead precompute a list of pixels inside the
brush mask and what neighbors they have. Switch from scalar double to
simd float.
Speedup (of the laplace part, excluding gamma correction): 10x-20x,
depending on brush size.

Add "linear" parameter to GimpApplicator. Pass the drawable's "linear"
to the applicator, and to all calls to gimp_gegl_mode_node_set_mode(),
instead of hardcoding FALSE everywhere.
Switch heal tool back to sRGB, which produces better quality than
linear-light. It is, after all, trying to correct for differences in
perceived brightness.
Fix heal tool's convergence threshold.
When we switched from [0,255] to [0,1] pixel range, the amount of numerical
error to tolerate should have been reduced proportionally.
which means adding a lot of proper API. Input, output and aux can be
pads or buffers. Make sure it uses the minimum possible graph in all
cases and doesn't reconfigure nodes unless needed. Port GimpPaintCore
to the new API.
Implement perspective cloning from a pattern. This needed quite some
refactoring, so GimpSourceCore would be able call its get_source()
vfunc also for a GimpClone subclass: essentially this commit adds a
new GimpSourceCore::use_source() vfunc that replaces the
source_options->use_source flag hack, and makes sure the graph used in
GimpPerspectiveClone's get_source() impl reads from the pattern
instead the drawable.
This version does not properly tile the pattern yet, so you can only
clone one copy of the pattern (gegl:tile is not quite doing the right
thing, so it's disabled).
