d3dx9: Introduce d3dx_pixel_format_id enumeration.
This MR contains a set of patches that move away from using D3DFORMAT
inside of struct d3dx_image
. This will allow us to support formats that do not have a direct mapping to D3DFORMAT
, and eventually once we share code with d3dx10/d3dx11 formats that do not have a direct mapping to DXGI_FORMAT
.
I've pushed a branch here containing patches that actually use this new internal format system in practice. I would've included those in this MR, but that seemed like it'd make for a rather large MR. Hopefully splitting it this way makes it easier to review. :)
