Bump version to 1.5.0.0
Add Intel 945GM support
Add RandR rotation support (full 3D acceleration, HWcursor & Xvideo rotated too)
Remove shadow framebuffer rotation code
Add a new LinearAlloc option to allow more offscreen memory to be allocated
for XVideo applications. This allows HDTV movies to be played via Xvideo.
