This backport of a 2013 Xorg fix changes miext/damage.c so that the
text functions (damageText, damage{Poly,Image}Text{8,16}) finally are
very similar to the changes that NX introduced in 2007 with
nxagent-3.0.0-28.

Fun fact: the original freedesktop bug mentioned below is from 2005
and the fix came in 2013...

Next commit will be the complete drop of NXdamage.c.

    damage: Don't rewrite Text ops to GlyphBlt ops

    There's no particularly good reason to, and it breaks Xnest.
