CHANGES IN FLTK 1.1.0
- Implemented full alpha blending under MacOS X.
- Added fl_create_deepmask() function to create an alpha
- Added fl_create_alphamask() function to create an alpha
mask from 8-bit data; under MacOS X this creates an
8-bit bitmask, while other OS's currently get 1-bit
screen-door bitmasks.
