Based on a long debug session with Kostya.

Based on a long debug session with Kostya.

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.

This makes the default of '1' more explicit than defaulting to '1' in
