[PATCH v4 0/7] MR8490: d3dx{9,10}: Beginnings of d3dx code sharing.

[Connor McAdams (＠cmcadams)]

These are the first steps towards code sharing, finally  :)

Patch 4 is a bit big, but it's just copying code from various source files into a single source file. I can attempt to split if if that's preferable for review purposes.

--
  v4: d3dx10: Use shared d3dx code in get_image_info when possible.
      d3dx9: Don't include d3dx9 header in d3dx_helpers.
      d3dx9: Get rid of ID3DXBuffer usage in d3dx_helpers.
      d3dx9: Move functions intended for code sharing into a separate source file.
      d3dx9: Introduce d3dx_image_file_format enumeration.
      d3dx9: Introduce d3dx_resource_type enumeration.
      d3dx9: Replace D3DFORMAT constants with enum d3dx_pixel_format_id constants.
