Functions
ReducedSize	KODI::VIDEO::GEOMETRY::ReductionOutputSize (unsigned int sourceWidth, unsigned int sourceHeight, unsigned int targetWidth)
	The extent ReduceFrame produces: targetWidth clamped to the source, the height following its shape, both even. Exposed so a GPU reducer can size its blit target the same.
bool	KODI::VIDEO::GEOMETRY::ReduceFrame (const ReductionSource &source, unsigned int targetWidth, ReducedFrame &out)
	Downscale a decoded frame to a small planar 8-bit YUV420 copy on the CPU, each output sample being the box average of the source samples it covers. False when the source is not describable, leaving out untouched.
