Currently several shaders need "DrawMatrix" techniques to support the possibility that the input texture is a "YUV" format. Also, "DrawMatrix" is overloaded for translation in both directions when it is written for RGB to "YUV" only. A cleaner solution is to handle "YUV" to RGB up-front as part of format conversion, and ensure only RGB inputs reach the other shaders. This is necessary to someday perform correct scale filtering without the cost of redundant "YUV" conversions per texture tap. A necessary prerequisite for this is to add conversion support for VIDEO_FORMAT_I444, and that is now in place. There was already a hack in place to cover VIDEO_FORMAT_Y800. All other "YUV" formats already have conversion functions. "DrawMatrix" has been removed from shaders that only supported "YUV" to RGB conversions. It still exists in shaders that perform RGB to "YUV" conversions, and the implementations have been sanitized accordingly.
