(svn r10241) -Codechange: CopyToBuffer now produces a buffer that is unreadable from outside the blitter, so the blitter can store anything he likes
-Codechange: added CopyImageToBuffer, which produces a readable buffer for screenshots
-Fix: 32bpp-anim now holds animation on transparent objects to avoid strange graphical effects
-Fix: 32bpp-anim now works correct on mouse-movement (it holds the palette animation correctly)
