Original commit message from CVS: * configure.ac: * gst/colorspace/Makefile.am: * gst/colorspace/gstcolorspace.c: * gst/colorspace/gstcolorspace.h: * gst/colorspace/yuv2rgb.c: * gst/colorspace/yuv2rgb.h: Duplicate the ext/hermes colorspace plugin, and remove Hermes code and GPL code. Fix for new caps negotiation. Rewrite much of the format handling code, and some of the conversion code. Basically, rewrote almost everything. This element handles I420, YV12 to RGB conversions. * ext/hermes/Makefile.am: * ext/hermes/gsthermescolorspace.c: Rename colorspace to hermescolorspace. Fix negotiation issues. Remove non-Hermes related code. This element handles lots of RGB to RGB conversions, but no YUV. * ext/hermes/gstcolorspace.c: * ext/hermes/gstcolorspace.h: * ext/hermes/rgb2yuv.c: * ext/hermes/yuv2rgb.c: * ext/hermes/yuv2rgb.h: * ext/hermes/yuv2rgb_mmx16.s: * ext/hermes/yuv2yuv.c: * ext/hermes/yuv2yuv.h: Remove old code.
