"""Run Direct3D 12 commands through vkd3d-proton on Raven and check the pixels the GPU produced.

testdata/d3d12/clear.exe creates a command queue, a render target and a read-back buffer, clears the target to (0.2, 0.4, 0.6, 1.0) with
|
|
ClearRenderTargetView, copies it into the buffer, waits on a fence and writes the buffer to a file. Every pixel must be (51, 102, 153, 255).
