Martin Storsjö	77e6293735	arm: Consistently use proper interworking function returns Use "bx lr", or "pop {lr}", which do proper mode switching between thumb and arm modes. A plain "mov pc, lr" does not switch from thumb mode to arm mode (while in arm mode, it does switch mode for a thumb caller). This is normally not an issue, as CONFIG_THUMB only is enabled if the C compiler defaults to thumb; but stick to patterns that can do mode switching if needed, for consistency.

Niklas Haas	ec9985b54f	swscale/internal: constify and expose ff_swscale() Used as an intermediate entry point for the new swscale context. The extra constification is a consistency measure, as I want to move the memcpy of stride and plane pointers to the functions that actually need to mutate them.

Niklas Haas	403a20b2e6	swscale/rgb2xyz: expose these functions internally Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>	3 months ago
Niklas Haas	775de8c19d	swscale/rgb2xyz: follow convention on image pointers and strides Instead of taking an int16_t pointer and a stride in halfwords, follow the usual convention of treating all planes and strides as byte-addressed. This does not have any immediate effect but makes these functions more reusable without unintended "gotchas". Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>	3 months ago
Niklas Haas	9d8f5141cf	swscale/rgb2xyz: add explicit width parameter This fixes an 11-year-old bug in the rgb2xyz functions, when used with a negative stride. The current loop bounds turned it into a no-op. Additionally, this increases performance on highly cropped images, whose stride may be substantially higher than the effective width.
