In Windows 10 it's possible to force the transfer function and colorspace
if the hardware supports it. This set of patches make use of this possiblity.
It gives much better result than manually handling them in the pixel shader.

I also reworked the range handling as it should be done after everything is
done, just before displaying.

The first few patches are doing some cleaning to prepare the next patches and
make debugging a little nicer.

Steve Lhomme (14):
  direct3d11: factorize the same string usage
  direct3d11: log the Pixel Shader stages in debug builds
  direct3d11: avoid passing through all the code for nothing in debug
  direct3d11: rename COLORSPACE_RGB_FULL as it's used for other things
  direct3d11: add a function to determine if a shader will be for RGB or
  direct3d11: fix typos in ST2084 pixel shader
  direct3d11: add support for transfer conversion for BT.709 and sRGB
  direct3d11: do the tone mapping for HLG sources too
  direct3d11: fix the HLG to Linear luminance
  direct3d11: only saturate before delivering the RGBA
  direct3d11: list the colorspaces supported by the swapchain
  direct3d11: pick the best swapchain colorspace for the source video
  direct3d11: rework the full/studio range adjustement
  direct3d11: adjust the max luminance based on the source and output
