In the screenshot plug-in, don't clean the image, since it's not
backed by any persistent source, and disable undo while modifying
it, so that the initial edit history is clean.
I realized having the revision as a build number is the wrong idea as it
implies packagers will have to rebuild GIMP for just a revision. Yet
very often revision may just be data change or dependency fix/update
without rebuild needed (i.e. no ABI change).
Instead let's keep this package information as a file 'gimp-release'
(inspired by /etc/os-release and other /etc/*-release files of
distributions).
In the Airbrush tool, increase the maximal stamp FPS from 15 to 60,
and change the corresponding maximal Rate value from 150 to 100.
This technically affects tool presets, but we'll live.
When downscaling raster brushes, we currently resample the original
brush with no fitlering (other than bilinear interpolation), which
results in very noticable aliasing when using heavily downscaled
big brushes.
This commit constructs a box-filtered mipmap hierarchy for the
original brush on-demand, and the closest mipmap is used as the
resampling source for downscaled brushes, significantly improving
the output quality.
... which converts a (scale, aspect_ratio) pair to a (scale_x,
scale_y) pair.
Change gimp_brush_transform_matrix() to take (scale_x, scale_y)
parameters, instead of (scale, aspect_ratio), and change the rest
of the code accordingly.
If for instance you've got no internet connection or other reasons that
a check might fail, the check-update-timestamp will be 0, which is
1970-01-01.
Thanks to Alexandre Prokoudine for noticing it!
When loading ABR brushes, error out on negative scan-line lengths,
instead of trying to allocate a huge buffer. This entire code
could use a whole lot more unsignedness, but this should cover the
crash.
Improve the efficiency of decoding RLE data when loading ABR
brushes, by reading entire scanlines into a buffer all-at-once,
instead of reading the stream byte-by-byte.
