          gdk-pixbuf/pixops/timescale.c:  Add Sun mediaLib support so that
          hardware acceleration via mediaLib is enabled if mediaLib is
          detected via configure.  Enhancement request #344813.  I was given
          permission to commit in the bug report by Matthias Clasen.
        * gdk/medialib.[ch]: New files added for mediaLib support.

          mediaLib support.

<para>
Scaling and compositing functions take advantage of MMX hardware
acceleration on systems where MMX is supported. If gdk-pixbuf is built
with the Sun mediaLib library, these functions are instead accelerated
using mediaLib, which provides hardware acceleration on Intel, AMD,
and Sparc chipsets. If desired, mediaLib support can be turned off by
setting the GDK_DISABLE_MEDIALIB environment variable.
