<pre>I can't see anything else to squeeze out of masked glyphs. It basically
requires 3 passes: (1) clear temporary mask, (2) render glyphs to mask, (3)
composite mask onto dst.
That of course doesn't help your situation where konsole is able to queue up
rendering faster than can be processed by the GPU. So I tweaked the cheat:

sna/glyphs: Add DBG option for glyph tolerance
And bump it to 3 so that glyph filtering doesn't force us to use the
mask too often.
