Directory full of pixel data scaling code that will eventually migrate
2000-01-05 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/: Directory full of pixel data scaling
code that will eventually migrate into libart.
* configure.in acconfig.h: Add checks for MMX compiler support
* gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
Nice wrapper routines for the code in pixops that operate
on pixbufs instead of raw data.
* gdk-pixbuf/testpixbuf-scale: Test program for scaling
routines.
