RenderViewport: Texture Format
When doing viewport rendering the color management happens on the CPU.
This has overhead in downloading a float texture from the gpu and
performing color management on the CPU.
Based on the scene fileformat bit depth the result will be rendered to
a byte texture where the colormanagement happens on the GPU or a float
texture where the colormanagement happens on the CPU.
This is only done during `Viewport Render Animation` in other
cases a float texture is being used.
