Change wording in Advanced Color Options drop-down menu to not imply
that GIMP isn't color-managed.
Slightly changed wording from Elle's original patch (mitch).
Also set the combo box' "ellipsize" property to END because it's too
wide. As mentioned before, this doesn't work for whatever reason,
hints are appreciated :)
when a click is detected by gimp_tool_check_click_distance(), only do
a motion() back to the button_press() coordinates if there has been a
motion at all since button_press(). This should not change any tool's
behavior, it's only an optimization to keep tools from doing useless
work.
The halftones transfer mode of dodge/burn uses pow(), which produces
NaN for negative input values. This tool doesn't really have OOG
values in mind, but using an odd power function fixes this issue,
and is in line with the behavior of the other modes w.r.t. OOG
values.
Spotted by José Americo Gobbo: when using a pattern source
for the clone tool, the top left corner was picked
as starting control point, which made the "fixed" aligment
rather useless. Using the pattern center allows the
better control of a pattern source.
Add a "mask-only" property to GimpBrushClipboard. When TRUE, only
create a brush mask (not a pixmap brush with mask and image).
Keep two clipboard brushes around: one classic "Clipboard Image" one
to be used as "stamp", and one new "Clipboard Mask" one that turns the
clipboard into a brush mask.
Fix the edit-paste and edit-paste-as-new-image PDB wrappers to use
gimp_get_clipboard_object(), not just clipboard_buffer(), and deal
correctly with entire images in the clipboard.
The GNOME sdk runtime used to be built which flags not appreciated by
older CPUs. This has now been fixed. Let's get rid of our workaround.

Integer overflows allow out of boundary writes while reading GIH files.
The checks are copied from file-gbr.c. In turn, the necessary gsize
casts are added in file-gbr.c, too. These are important on 64 bit
systems. Without these casts, the precision of the calculation is still
32 bit, allowing overflows.

SVG icons won't be properly displayed with an older GTK+. See:
https://bugzilla.gnome.org/show_bug.cgi?id=781020
Note: 2.24.32 is not out yet, but it will be the first stable release
with the right fix.
If a PCX file contains a bytesperline entry which is too small, it is
possible to trigger an out of boundary read, which can lead to a
segmentation fault.
The bytesperline validation is incomplete. While checking if enough
bytes per line exist, the integer truncation during the division must be
taken into account.
An example would be a 1x1 PCX file with a bpp of 1 (monochrome). The
current check allows a bytesperline field of 0, which in turn would lead
to a 0 byte allocation in load_1. Yet, the code would access index 0.

If either width or height is 0, gimp won't process the PCX file.
Instead, a bunch of error messages are printed.
It's nicer to quit parsing the file early on with a good error message
which is straight to the point instead.

Fix brush shrinking used to compensate for the blur: avoid over-
shrinking the brush and changing its aspect ratio.
Change the way hardness maps to blur radius: hardness == 0 maps to
the largest radius such that, when the kernel is applied to the
middle pixel of the brush, the kernel is completely within the brush
bounds, taking brush shrinking into account, *assuming the brush is
a circle*.
Use the dimensions of the unrotated brush when calculating the blur
radius, so that rotation doesn't affect the blur amount (the blur
itself is not isotropic, though, and is applied after rotation, so
while the blur amount remains uniform, its effect does depend on the
brush angle.)
Get rid of the blur-radius upper limit -- it's fast enough to handle
large radii now.
A few additional minor speedups.
Also, make sure we don't overflow for large blur radii. Not a
problem yet, since the blur radius is capped, but soon...
Add a specialized convolution algorithm for the hardness blur. It
uses the same kernel as before, but performs the convolution in
(amortized) O(1)-per-pixel time, instead of O(n^2), where n is the
size of the kernel (or the blur radius).
Note that the new code performs the convolution in the input color
space, instead of always using a linear space. Since our brush
pixmaps (but the not masks) are currently perceptual, the result is
a bit different.
