Show Liu Sept. 11, 2020, 8:55 a.m. UTC 
Add OpenGL fragment and vertex shaders to convert two- and tri-planar
YUV formats to RGB. This will be used to accelerate YUV image rendering.

Would this be more readable ?

	mat3 yuv2rgb_bt601_mat = mat3(
		vec3(1.164,  1.164, 1.164),
		vec3(0.000, -0.392, 2.017),
		vec3(1.596, -0.813, 0.000)
	);

Apart from that,

If you're fine with this change I'll handle it when applying the series,
no need for a v7 just for this.
