drop internal support for 1-bit images

on modern hardware, these are less efficient than regular alpha
channels.

Also, this greatly simplies the range of stuff that vcl needs to deal
with, which will make the upcoming transparency->alpha patch easier to
deal with.

Enhance vcl::CreateFromData to convert incoming 1-bit data to 8-bit
image.
