It's unused since keithp's copy acceleration code completely replaced
glamor_copyarea.c and removed the blit path.

GetGlyphs is supposed to always return the full list of characters
when there is a default character available. However, if an
application opens a 16-bit two dimensional font and then draws with
8-bit requests, the bitmapGetGlyphs function in libXfont versions up
through 1.4.7 will return zero glyphs if there is no 0th row.
While this is a bug in libXfont and should be fixed there, it's easy
to protect glamor from it by simply falling through to the case that
handles GetGlyphs failures for fonts without a default character.

Was interpreting the incoming chars as 8-bits instead of 16-bits,
resulting in the wrong characters being drawn.

Now that we have the DIX global state for the current context, we
don't need to track nesting to try to reduce MakeCurrent overhead.
v2: Fix a mistaken replacement of a put_context with make_current in
glamor_fill_spans_gl() (caught by keithp).

Accelerates text painting with GPU-based geometry computation and stippling
v2: Simplify get_glyphs, expand single character variable names to
more descriptive ones. (Markus Wick)
v3: Rebase against the glamor_prepare_* un-renaming (changes by anholt).
