Partial fix for semitransparent glyph outlines.

This fix removes semitransparent area (less then pixel width) between glyph and
it's outline. Instead, it makes them overlap a little. It usually looks much
better this way.
Complete fix seems impossible with the current output format (single color
alpha bitmaps). The right way is to blend both glyph and outline into one
bitmap so that 2 pixels with 50% transparency produce a fully solid one.
This requires RGBA bitmap output from libass.
