CVS Update (YUV, clipping, etc.)

SDL Development
1

The latest SDL CVS snapshot is now available:
http://www.libsdl.org/cvs.html

Changes:
* Replaced useless SDL_SetClipping() with SDL_SetClipRect()
* Fixed visual detection in XVideo handling (crashed smpeg)
* Added a flag to YUV overlays to show hardware support
* Added SDL_WasInit() to see what is currently initialized
* YUV overlays can now be accelerated with DirectX

I’ve changed the clipping semantics so that clipping affects the
destination surface instead of the source surface, and blit clipping
is now essentially free. Mattias, can you scan the clipping code to
make sure it’s good? I wrote it at 2:00 AM. :slight_smile:

Everybody, should SDL_FillRect() be clipped by the clipping rectangle
the way SDL_BlitSurface() is now?

See ya!

Yes, definitly. I’d give reasons but my mind has gone blank. I suppose a
filled rect is just like a solid color blit or something.

For consistency reasons:

YES!

That means: When you define a cliprect every operation
should be clipped to that!
