@SYMTestActions Test actions are:
Create pseudorandom initial contents, source and mask lines.
Set a line of the screen to the initial contents.
Use FastBlendBitmapMasked, with and without inverted bitmask, to write
source to target.
Read line contents back.
Check each pixel is either the initial value, or the source or a blend,
