which removes a rectangle from the handler's dirty region, for cases
where the caller knows that the rectangle has been explicitly
constructed. Only needed by the gtk3-port branch.
and separate the chunk rendering logic from the fact that it's invoked
from an idle callback. Idle rendering no longer works in GTK+ 3.8 and
later because the expose logic was changed from an idle function to a
frame clock, and when we switch to that in gtk3-port, the diff to
master should stay readable (and rebasable) in this critical part of
the code.
Improvements:
- setenv/getenv() are not thread-safe, hence they should be run only at
startup before any threading occurs.
- it is counter-productive to load the huge ISO-639 XML file each time
the user opens the Preferences dialog or the text tool options.
The main change is that even with only 1 image in single window mode,
there is now a tab.
Also whatever the number of images when you hide docks with Tab, no tabs
are shown.
- Takes 2048 samples instead of 256 to handle properly large palettes.
It gives also better results with gradients.
- linearly interpolate values between two samples when
mapping with a gradient, to handle properly float precision.
Some languages have no 2-letter ISO-639-1. This is the case in particular
for 3 languages we have translations for: ast (Asturian), csb (Kashubian)
and nds (Low German), which have only 3-letter ISO-639-2/3 codes.
They were not visible in the list of languages in the Preferences dialog
until now.
setenv() does not behave well on some systems, in particular OSX (and
probably some BSDs), when the set value is NULL. In this case, let's
unsetenv() the environment variable instead.
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.
Make sure an indexed image always has a colormap. This was the case
before, except one could set a NULL colormap via the PDB.
Add gimp_image_unset_colormap(), and make gimp_image_set_colormap()
never set the colormap to NULL, even if NULL is passed. Change the
only places where actual unsetting makes sense to use unset().
Make some GUI places deal gracefully with palettes/colormaps with zero
entries.
So it works with all GObject versions, until we determine how useful
it is generally, and what API it should get for possible
libgimpwidgets inclusion.
Small fix for the last commit: set a silly small initial size request
on the wrap_box so it doesn't initially request too much and breaks
dock layout deserialization.
gimp_container_grid_view_viewport_resized(): set the wrap_box'
required width to just one cell_width, not cell_width * columns. This
way it can shrink also when attached to a toolbox dock. It remains
unclear why it could nicely shrink in all other dock columns.
Shells can now travel from one window to another. Canvas position code
should therefore not keep track of the image window for a specific shell
but must use whatever is the current window for this shell (even though
it may be a different one before and after the size-allocate).
This also partly fixes some positioning issue during mode switch.
during an image rescale, while spinning the main-loop,
layer-groups preview generation used to start before their
layers were fully rescaled, so it tried to access tiles that
were not yet there
