Patch version 3, this time split up since these are two different semantical
changes now.

0001-render-set-the-glyph-picture-to-NULL-by-default.patch
    Hunks 1 and 2 of the previous patch plus an early exit when trying to
    composite a NULL source.
0001-render-Fix-crash-in-RenderAddGlyphs-23645.patch
    The actual fix to 23645, same as the original version.

Cheers,
  Peter
