You can now set any paint tool to mirror painting relatively
horizontal/vertical axis or a central point (any combination of these 3
symmetries).
This has been implemented as a new multi-stroke core, where every stroke
is actually handled as a multi-stroke (default of size 1).
This is also the first usage of custom guides for symmetry guiding.
Current version has to be activated in the playground.
Remove the code that links size, spacing etc. to brush defaults from
the GimpPaintOptions class impl and add it to gimppaintoptions-gui.c
as a callback instead.
It's not a core thing and that magic with side effects should only be
applied to the GimpPaintOptions behind the tool options GUI.
This adds a boolean to GimpCoords struct that is true for enabled
extended non-mouse devices and false for all the rest allowing
the mypaint brush to override the the pressure sent to the paint library.
This (doesn't quite) fix an obscure part of the tool preset bugs: when
changing the brush on a GimpPaintOptions instance, we might or might
not change the brush size, aspect etc. to the set brush's native
values, possibly overwriting the intended values from a tool preset.
Implement GimpConfig::copy() and copy the affected values again after
the entire object has been copied, so we actually use the value of
gimp_config_copy()'s "source" object.
This would fix that particular tool preset problem if there wasn't
another bug that is still unfixed, stay tuned...
This reverts commit 15b5b2c8b3.
This feature is "undiscoverable" according to Mitch, and we are not sure
how much the endpoint colors are special to the user.
Now the history of recently used colors is not updated when selecting
in the color dialog anymore, but when a color is actually used.
Tools supported right now are: Ink, MyPaint brush, all PaintBrush tools,
bucket fill and eraser (background color on non-alpha drawables).
Moreover from now on, colors already saved are properly moved to first
position when reused.
Implement GimpConfigInterface::duplicate() and after duplicating the
paint options, copy the brush-related properties again, because they
might have been changed by setting the brush on the copy (if they are
set to be linked to the brush's native values).
The work-in-progress was using a source tree of libmypaint embedded
into GIMP tree. This is a cleaning with pkg-config test in configure,
and correct includes.
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.
