Description Kimmo Kinnunen 2023-03-01 05:34:05 PST 
ImageBufferIOSurfaceBackend bitmap draws spend time maintaining the color conversion cache

This happens for small bitmaps when they're color matched to the destination bitmap.
This is redundant as the cache never gets hit since the images are transient.
Mark the images transient.
