+Summary: gamma correction plugin should handle RGB
 
 Due to a very old monitor i need gamma correction to see anything when
 playing video. gst was missing such a filter, so i wrote a simple one.

+I modified the patch to fit in with recent changes I made to
+make_filter, and applied it.  Thanks for sending it.
+
+I tested it out, and I'm a bit worried that it doesn't work very well
+in YUV space.  That's not surprising, since gamma correction is
+typically done in RGB space, since monitors are non-linear in RGB space.
+
+I'm leaving this bug open, but retitiling it to reflect that it would
+be better to have an RGB gamma plugin.
