Build Testing With DX12 Reserved For Windows 10

[vlj]

I have the depth buffer rendered in the bottom right hand corner too, I'm not sure why since it should be set by the scale/offset value.

I enabled mrt read/write. Similar to depth_read, when context_dma_color_a/b/c/d changes, or when a semaphore is released, the content of the color buffer is written to.
The cube_mrt.ppu.elf test should work properly now.
