Scaling Functions that Leave R1 Dirty

Detailed Description

These functions are more efficient for scaling multiple bytes at once, but require calling cleanup_R1() afterwards.

Collaboration diagram for Scaling Functions that Leave R1 Dirty:

Functions
LIB8STATIC_ALWAYS_INLINE void	cleanup_R1 ()
	Clean up the r1 register after a series of *LEAVING_R1_DIRTY calls.
LIB8STATIC_ALWAYS_INLINE void	nscale8_LEAVING_R1_DIRTY (uint8_t &i, fract8 scale)
	In place modifying version of scale8() that does not clean up the R1 register on AVR.
LIB8STATIC_ALWAYS_INLINE void	nscale8_video_LEAVING_R1_DIRTY (uint8_t &i, fract8 scale)
	In place modifying version of scale8_video() that does not clean up the R1 register on AVR.
constexpr CRGB	nscale8x3_constexpr (uint8_t r, uint8_t g, uint8_t b, fract8 scale)
LIB8STATIC_ALWAYS_INLINE uint8_t	scale8_LEAVING_R1_DIRTY (uint8_t i, fract8 scale)
	This version of scale8() does not clean up the R1 register on AVR.
LIB8STATIC_ALWAYS_INLINE uint8_t	scale8_video_LEAVING_R1_DIRTY (uint8_t i, fract8 scale)
	This version of scale8_video() does not clean up the R1 register on AVR.
