Mouse Input On Windows
ioq3 uses SDL to abstract away as much as possible from platform specific
implementation details. Unfortunately, SDL 1.2 suffers from a number of bugs
and limitations with respect to mouse input on the Windows platform. We
provide a patch against the SDL subversion 1.2 branch which fixes the
following problems:
* DirectX (and thus DirectInput) driver not functional when using an
OpenGL SDL_Surface.
* DirectX (and thus DirectInput) driver not functional in windowed mode.
* Mouse buttons 4-7 unusable with the DirectX driver due to DirectInput 5
not exposing the required functionality. Use DirectInput 7 instead.
* Low quality mouse input data when using the windib driver due to use of
WM_MOUSEMOVE events. Use GetCursorPos API call instead.
The patch can be found in misc/sdl-win32-fixes.diff.
PNG support
ioquake3 supports the use of PNG (Portable Network Graphic) images as
textures. It should be noted that the use of such images in a map will
