Cool.

Michael Emmel wrote it originally, but hasn't touched it recently and no
other maintainer has really stepped up. So I think we're in a
whoever-touched-it-last situation here:

$ git shortlog --since='6 months ago' -- src/cairo-directfb-surface.c
Behdad Esfahbod (1):
      [cairo-xlib] Fix show_glyphs when failing to upload a glyph

Claudio Ciccani (1):
      [cairo-directfb] Fixed bug in clone_similar() (src_x added twice).

Looks like you're not going to find anyone to object, Vlad, (and if you
do, then you've found a maintainer).

Commit away!
