		* This command has the following binary layout in bytes:
		*
		* 0 - 16 * 4: matrix
		*
		* Sets a matrix for color transform which will be applied on this layer
		* before composition.
		*
		* If the device is not capable of apply the matrix on this layer, it must force
		* this layer to client composition during VALIDATE_DISPLAY.
		*
		* The matrix provided is an affine color transformation of the following
		* form:
		*
		* \|r.r r.g r.b 0\|
		* \|g.r g.g g.b 0\|
		* \|b.r b.g b.b 0\|
		* \|Tr Tg Tb 1\|
		*
		* This matrix must be provided in row-major form:
		*
		* {r.r, r.g, r.b, 0, g.r, ...}.
		*
		* Given a matrix of this form and an input color [R_in, G_in, B_in],
		* the input color must first be converted to linear space
		* [R_linear, G_linear, B_linear], then the output linear color
		* [R_out_linear, G_out_linear, B_out_linear] will be:
		*
		* R_out_linear = R_linear * r.r + G_linear * g.r + B_linear * b.r + Tr
		* G_out_linear = R_linear * r.g + G_linear * g.g + B_linear * b.g + Tg
		* B_out_linear = R_linear * r.b + G_linear * g.b + B_linear * b.b + Tb
		*
		* [R_out_linear, G_out_linear, B_out_linear] must then be converted to
		* gamma space: [R_out, G_out, B_out] before blending.
		*
		* @param matrix is a 4x4 transform matrix (16 floats) as described above.
