Since wlroots almost always significantly breaks API each minor release,
allowing parallel installation of wlroots helps packagers deal with
programs that require conflicting versions of wlroots.

An editorconfig's asterix section applies to the whole file tree,
including the .git folder. The Git commit message dialog is a temporary
file named .git/COMMIT_EDITMSG, which the editorconfig applies to.
To avoid having the line length of commit messages changed to 100 chars,
add a rule to specifically unset the max_line_length for the .git
folder.
If we need to apply a color transform to rendered content, we will not
be able to use direct scanout. Explicitly skip it to not accidentally
show frames lacking the color transform.
e08d52bb introduced a bug when rotating by 90 or 270 degrees and doing
non-uniform scaling (different scale factor on X and Y axes). The scale
factor was calculated as the ratio between the src box and the rotated
dst box. But scaling is applied after rotation, so the scale factor
should instead be the ratio between rotated src box and dst box.
Reverts 77006e5565. It turns out this
change really breaks the labwc drop-shadow implementation (which relies
on scaling up single-pixel-wide buffers).
After reverting this there's still something subtley wrong with scaling
pixel locations (shown by `weston-scaler -b`) but I can't see an obvious
way to make both weston-scaler and labwc drop-shadows work in the same
way with pixman and gles2. I'll have a harder look at this but in the
mean time reverting this patch seems to make things less broken on
average.
The DRM backend's set_cursor function always return true if the
buffer is NULL. If using a NULL cursor's buffer on startup, the
wlr_output_cursor will be marked as a hardware cursor. If the
cursor later gains a non-NULL buffer and the DRM backend rejects
that buffer, the cursor will remain marked as a hardware cursor,
despite the backend not displaying it as such. As a result, the
cursor will not be displayed at all. Fix this by always resetting
the hardware_cursor field in output_cursor_attempt_hardware().
Even if the backend advertises dri3 support, querying the DRM FD may fail.
Instead of returning early, the backend creation process must continue because
shm might be supported.
UNDEFINED when used as source layout means that the contents of
the underlying memory becomes undefined. This isn't what we want
here: we don't want to mutate the imported pixel data.
The Vulkan spec isn't really clear what the proper value should be
here, but after discussing with driver developers [1] it seems like
UNDEFINED isn't the right one. The recommendation is to use GENERAL
instead.

This has been introduced way back in
be297d9d14 but is never used anywhere.
If compositors want to save the old dimensions before reacting to a
fullscreen or maximize event they can just grab the sizes within their
event handlers instead.
The old code to render transformed textures with pixman would run
composite over the whole output regardless of the texture size. When
rendering something small this caused a huge performance hit.
Rewrite the transform branch of render_pass_add_texture to:
- Only composite over the rectangle we're drawing to
- Generally try to make things a lot clearer and some comments

This change makes it possible to support both the direct srgb-format
pipeline and indirect (color-managed, or non-srgb-format) pipeline
for the same render buffer.
Fix source crop in the pixman render backend. It was being applied by
using a source offset as arguments to pixman_image_composite32(). But
this is wrong because the source crop should get applied before all the
other transforms, not after them (or at least this is how it works in
the other wlroots render backends). Instead, apply the source crop as
yet another matrix transform when we're doing transforms (Or keep it the
same as previously if there's no other transforming going on).
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3830
The translations for flipped offsets were set the same as non-flipped
ones which was totally wrong and meant that any textures with
flipped-transforms rendered entirely outside the viewport and were
basically invisible.
