◆ DECL_FUNC() [2/2]

DECL_FUNC	(	linear_mask	,
		const uint32_t	mask
	)

Fully general case for a 5x5 linear affine transformation.

Should never be called without constant mask. This function will compile down to the appropriately optimized version for the required subset of operations when called with a constant mask.
