Description from that PR
Make xorg apps look as intended. Most notable change: xmag color picker is usable now.
Before this commit, only two apps had properly configured resource paths: bitmap and xcalc. This commit automates and generalizes it to the rest of xorg.* apps.
xorg.bitmap: bin/bitmap-color is no longer installed. If you would like bitmap to be viewable in color, please refer to man 1 bitmap, selection COLORS. The described method is also applied to some other affected apps.
The new derivation should evaluate only if the old derivation does.
Sadly this means that the old derivation cannot depend on the new one
any more, which was used by xorgserver on Darwin. But this is not a
problem as `overrideAttrs` can (and should) usually be used instead.
This change allowed catching an invalid `meta.platforms` in the linux_rpi
kernels, which use `overrideDerivation`.
Previously, Darwin was kept on 1.18 because more recent versions were
broken, but now 1.18 is also broken on Darwin, so we might as well get
rid of the special case and bring Darwin forward. With these changes,
xQuartz builds on Darwin, but when run it will exit immediately.
This makes Darwin use the same derivation as Linux by default, which
will enable further cleanups. But as a result, we have to fix some
Linuxisms.
* Only add libdrm dependency on compatible platforms.
* Add libepoxy dependency for all platforms.
* Add bootstrap_cmds dependency on Darwin.
* Disable glamor on Darwin.
Package bump:
- Grabs are now deactivated on Xwayland, leaving them to the compositor
- Memleak and length-check fixes for xkb
- Fix for kinetic scrolling
- Delayed wl_surface destruction to fix a race

it appears that the configure script isn't checking
`${ac_tool_prefix}cpp`
```
for ac_prog in cpp
do
# Extract the first word of "$ac_prog", so it can be a program name with args.
set dummy $ac_prog; ac_word=$2
