    …If you need the old behavior, you can edit fastled_config.h and change FASTLED_NOISE_FIXED to 0. Fixes #416.  Thanks to everyone who reported this and helped track it down.

    … a little smaller than the C version; it also preserves one additional low-order bit of precision so while it may not give exactly the same numeric results as the C in all cases, it presumably gives 'better' (smoother) ones.

    …lways inline', as it probably should have been previously, since it results is smaller and faster code in almost every case, since the body is only about 12 AVR instructions. ATtiny uses 'C' version since the AVR assembly code uses the hardware multplier, which the 12-years-old-now ATtiny doesn't have.

    …be a little smoother now and free from error noise in the low bits. This includes palette colors returned from ColorFromPalette, which are now slightly smoother. Also introduced a new lib8tion function, blend8( byte, byte, fract8). The new pixel blending should have negligible effect on code size, and it is ever so slightly faster than the old version with the error. Fixes #404.
