Except for bitmaps, charblit_v, and the ability to rotate/unrotate at runtime, the
rotation code in CVS now works. I'll post a screenshot as soon as bitmaps work.
To keep it simple and fast, I am going to use the same code that will be used to
translate bitmaps to a new driver's format to rotate the bitmaps when the screen is
rotated. This way, no special blit needs to be made. (Except maybe a sideways
scrollblit)
To facilitate this runtime bitmap rotating and translating between drivers' formats,
each driver will be able to convert bitmaps to and from a common format (probably
linear 32-bit color) and the new driver can convert that to its format. The only time
this causes a problem is that when a low-bpp image is converted to a higher-bpp image
it won't show an improvement. For most apps I wouldn't think it would matter too much
as they would load images after converting bpp, but the apps will get an event so they
can reload things if necessary. This will be especially important for themes.
