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. 2000-01-05 21:33:58 +00:00			`.file "have_mmx.S"`
