+ * configure.ac:

+ * 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/yuv2yuv.c:
+ * ext/hermes/yuv2yuv.h:
+ Remove old code.
