texcoord is unused in the rounding part of the textureshaders.
QUADFRAGSRC isn't using that variable inside the non rounding code.
Because of that opengl optimizes that variable out, and is complaining
if glGetAttribLocation is called on it.
this makes for a far better experience in combination with wlroots,
since that whole makefile mess is not required.
Additionaly, handling of wayland protocol sources is also slightly
better, but could be improved with mesons inbuilt wayland module.
To build Hyprland using meson:
meson _build -Ddefault_library=static
ninja -C _build
ninja -C _build install
