ffmpeg | branch: master | Carl Eugen Hoyos <cehoyos at ag.or.at> | Thu Oct 30 10:22:34 2014 +0100| [792f0f20456cc24f1f1b9ee445e50737d65e38df] | committer: Carl Eugen Hoyos

Fix compilation of xcbgrab if xcb/shape.h is not available.

Old versions of libxcb do not provide xcb_shape_rectangles().
The issue can be fixed differently but this small change fixes
some fate platforms and a user reported compilation problem.

Reported and tested by trac user kevmitch.
Fixes ticket #4067.
