This patch also adds a Format concept to GraphicsBitmap. For now there are only two formats: RGB32 and RGBA32. Windows with alpha channel have their backing stores created in the RGBA32 format. Use this to make Terminal windows semi-transparent for that comfy rice look. There is one problem here, in that window compositing overdraw incurs multiple passes of blending of the same pixels. This leads to a mismatch in opacity which is obviously not good. I will work on this in a later patch. The alpha blending is currently straight C++. It should be relatively easy to optimize this using SSE instructions. For now I'm just happy with the cute effect. :^)
