Subject: util-x11: Rework init_window interface to accept XVisualInfo
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=6014e77b9f7cf0570fe799fde240970a7cafb7ce;hp=6014e77b9f7cf0570fe799fde240970a7cafb7ce;p=fips

util-x11: Rework init_window interface to accept XVisualInfo

This is a much more correct way of doing things. Previously, we would select
a visual when creating the OpenGL context, but then use a default visual when
creating a window. This was fragile and would fail if the default visual was
not identical to what we had created.

Now, instead, we pass the selected XVisualInfo to our init_window interface
and call XCreateWindow instead of XCreateSimpleWindow. This guarantees that
the visuals match as required.
