We should be using the EGL renderer's colorspace and color range
rather than the backend renderer's for fallbacks. The former is
what actually gets passed to the host PC during stream init.
The platforms that would most benefit (embedded V4L2 decoders)
either don't use frame pooling or don't synchronize with
modified DMA-BUFs unless eglCreateImage() is called each time.
Importing composed formats is more efficient and performant because it allows
tiled and/or compressed surfaces to be directly sampled by shaders without
requiring a conversion to a linear planar format first.
