Load or save a single-plane Mask.
Loads: Yes
Saves: Yes
Autodetect: No
This GIO is intended to make the life of programmers a bit easier... You can load and save single bitplane masks (for use in Blitter Masks and the like) directly from 24-bit images. This GIO supercedes the "CreateMask" effectSelect the "background" colour using the colour dropper and keep this locked as the current selected colour. All pixels of this colour will be sent to '0' in the bitplane. All other pixels will be set to '1'.
When loading you will need to specify the size as the saver does not save any headers (just 1-plane RAW)
