vcl-svp: Store 24-bit images in 3-byte pixels
This adds support in headless rendering for more
compact 24-bit RGB image storage in 3-byte pixels
instead of 4 bytes.
There is a conversion necessary to accomodate Cairo,
which requires 4-byte pixels, but that is relatively.
Early tests show no loss of performance at runtime.
Unit tests updated since the bitmap memory bytes
are crc-ed, which obviously are different in size
if not in content.
