Title: Custom character width detection fix.

Uses Alpha instead of Green channel to determine opacity in a custom font texture, allowing characer widths to be determined correctly.

Also trims most of the 'garbage' off of fullwidth characters, though with large font textures (1024^2) a single column of garbage pixels will remain.

Changed 'colIdx' back from 'pixel' to maintain consistency with pclewis/mcpatcher.
