Patch 3:
-            upload_palette(src, context);
+            upload_palette(src, dst, context);

What does the interface you plan look like?

I had a short look at this and my proposal is to separate the blitters into 
two interfaces: One that sets the shader for the color conversion(blit_shader 
without colorfill and depthfill), and one that does the drawable setup and 
initiates the data transfer(That could include blitters that call 
glTexSubImage2D when blitting from sysmem->vidmem)

The shader setup blitter could be hidden behind a quad draw blitter if you find 
a way to integrate swapchain_blit and surface_blt_to_drawable(especially 
frontbuffer texture -> frontbuffer drawable blit)
