- Added a framework for drawing the 2D screen elements with Direct3D textures.

They are not actually drawn with it yet, nor is it complete, but it's
  something to start with.
- Split up DCanvas::DrawTexture() into more pieces to make it easier to
  virtualize.
- Removed support for non-32-bit palette textures from D3DFB. What kind of
  card supports pixel shaders but not 32-bit textures?
