can you explain the backend consequence of the different Render Qualities:
** Render qualities
kPrRenderQuality_Max = 4,
kPrRenderQuality_High = 3,
kPrRenderQuality_Medium = 2,
kPrRenderQuality_Low = 1,
kPrRenderQuality_Draft = 0,
kPrRenderQuality_ForceEnumSize = kPrForceEnumToIntValue
And how orthogonal it is to the PixelType requested?
For example, one would assume that Draft mode should work as fast as possible by using the YUVA_8u PixelFormat whereas MAX mode would work in YUVA_32f and thus YUVA_32f PixelFormat should be requested in the supported PixelFormat type supported by the Exporter.
Always asking for YUVA_32f is a waste of processing time so that shouldn't be at the top of the supported PixelFormat list unless you really want it at max bit depth.
As an example - the shipped "h.264" exporter has a "Render at Max Depth" button. What RenderQuality does it set and what PixelFormat does it put in the list - and in which order - when enabled and disabled?
