Hi,

I have just made a patch to add bitmap support to Video API. It contains
example bitmap loader for .tga files. At this point there is no real
example how to use them, but I have tried to update wiki to reflect
changes (except that bitmap handling is not there yet).

New functionality was introduced to Video API to specify blitting
operator. Now there is only two operators specified, replace and blend.
Replace just uses source pixel data and blits it destination and blend
uses source pixel alpha value to blend source and destination pixels.

Reason why I wanted to give patch before better example how to use is
ready is that I want it to get to next grub release and I don't want to
block other development. And I didn't include that background bitmap
loading to gfxterm in this patch as I would rather like some development
to improve menu system than to stall it :).

Patch is attached to this message, any comments are welcome.

Thanks,
Vesa Jääskeläinen
