I'd been considering it for a while, but in the end, all the issues it
presented made me decide it wasn't worth merging and was never really
worth keeping: it was a neat proof of concept but of little actual use,
especially now everyone either has an OK GPU or would want to stick to
8-bit rendering anyway (sorry L-Havoc).
However, both it and my merge work are preserved in git history :)
I got tired of having to maintain two separate software renderers, but
didn't want to just nuke sw32, so its core changes are merged into sw.
Alias model rendering is broken, but I know exactly what's wrong and how
to fix it, just need to take care due to asm.
It seems X11 does not like creating barriers entirely off the screen,
though the error seems to be a little unreliable (however, off the left
edge was definitely bad).
This should be a much friendlier way of "grabbing" input, though I
suspect that using raw keyboard events will result in a keyboard grab,
which is part of the reason for wanting a friendly grab.
There does seem to be a problem with the mouse sneaking out of the
top-right and bottom-left corners. I currently suspect a bug in the X
server, but further investigation is needed.
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
viewport. This should fix the uncetnered viewport when going fullscreen.
Also discard mouse events caused by fullscreen toggling to avoid chaning
orientation.
