Skip border generation if glyph is collapsed

If a character is completely collapsed in x or y direction (\fscx0,
\fscy0), the rasterizer will not generate any visible pixels. This also
means vsfilter will never draw any border in this case, since it works
on the pixel data. FreeType's stroker OTOH happily draws a border around
a character, no matter how collapsed it is. Emulate vsfilter's behavior
by skipping border generation if the glyph is collapsed.
