Original commit message from CVS: * gst/alpha/gstalphacolor.c: (gst_alpha_color_base_init), (gst_alpha_color_transform_caps), (gst_alpha_color_set_caps): Double-check that RGB input caps are really RGBA caps (apparently the core doesn't always catch it if those caps aren't a subset of our template caps, also see #421543). Fixes #429319 in a way. Also, don't leak the pad template in the transform_caps function. * tests/check/Makefile.am: * tests/check/elements/.cvsignore: * tests/check/elements/alphacolor.c: (setup_alphacolor), (cleanup_alphacolor), (create_caps_rgb24), (create_caps_rgba32), (create_buffer_rgb24_3x4), (create_buffer_rgba32_3x4), (GST_START_TEST), (alphacolor_suite): Add some basic unit tests for alphacolor.
