cursor: reflects the above; much simplified now.
ogl_tex: preserve all texture state across reloads. add quality
mechanism (perf boost on older cards). split up upload code. add
ogl_tex_transform(). add more docs.
renderer, GUIrenderer, unifont: bring in line with ogl_tex changes (int
-> uint and call setters before ogl_tex_upload)
GameSetup.cpp: add tex quality mechanism
