We do extra work here to make the introspection scanner pick up
the docs for the static inline function, but that doesn't make the
function actually work in language bindings, so mark it as skip.
Fixes: #6298
According to EXT_color_buffer_half_float it should be renderable, but it
fails to glGenerateMipmap() with Mesa 23.3 so just pretend it's not
renderable until that is fixed.
Fixes CI from failing.
I naively assumed the EXT_color_buffer_float and
EXT_color_buffer_half_float extensions would mirror each other, but they
do not. The float extension explicitly excludes RGB32F from the
renderable formats.
These are not usable outside of GTK, so lets not burden bindings
with them.
I'll keep the get_child() function exposed, since it is needed to
iterate over node trees containing subsurface nodes.
asan randomly failed when this almost correct code wasn't quite correct.
Hopefully this is the correct incantation to compute the size.

The test ensures that offscreens render to the same pixel grid as the
actual image, and they are not offset by fractions of a pixel.
The Cairo renderer fails here because Cairo's clipping code rounds pixel
values wrong.
This is mostly untested and a result of reading the code.
The main effect here happens when a node was drawn that didn't start on
an integer boundary, which is very rare.
However, with specially crafted tests and when using fractional scaling,
this can happen.
This happened most often when clipping by the node bounds to restrict a
push_group() call. Enlarge that rectangle to fall on a pixel boundary.
Testcase included
The code was writing invalid memory, so this might not have always
crashed, but I did my best to write the test so it causes a SEGV.
Also included is a fix for the testsuite where the expected result was
wrong.
The replayed node/images weren't saved.
I wanted to check that an optimization is done when replaying a test,
but without a saved node file, I couldn't.
It is not material to this test, and it causes some hard to
understand problem with fontconfigs use of mmap, leading to
a sporadic segfaults in pangos fontconfig thread.
This test fails on my system currently, since rawhide libpng appears
to have changed the encoding of pngs so that the texture nodes no
longer match the reference. This will be a problem as long as our
ci systems have an older libpng, so disable this test for now.
Add a new activate signal that fires when enter is pressed after
editing, and make the default handler activate the default widget if
activates-default is set.
* Fix a bug where a zero increment would make the value unsettable,
when the more natural operation is to allow any value to be set.
* Factorise gtk_spin_button_snap into two parts (snapping + setting),
and make gtk_spin_button_snap only perform the snapping part.
* Avoid duplicate calls to gtk_adjustment_get_{lower/upper} and
reinvention of CLAMP macro.
These 2 rectangles used to intersect fine:
0 0 50 50 / 50 0
0 0 50 50 / 0 50
But the computed result was:
0 0 50 50 / 50
which is not a valid rectangle, because the corners overlap.
Make sure such rectangles return NOT_REPRESENTABLE.
The above rectangle has been added to the testsuite.
