+/** Finds or creates a final fragment program.
+
+	The fragment program is constructed by appending the shader compiler output
+	with output register conversion and blending code.
+
+	When this program is no longer needed, it should be released by calling
+	#sceGxmShaderPatcherReleaseFragmentProgram().  The caller is responsible for ensuring that
+	the GPU is no longer using this program before it is released.
+
+	Blending/masking is only supported for the output register formats
+	#SCE_GXM_OUTPUT_REGISTER_FORMAT_UCHAR4 or #SCE_GXM_OUTPUT_REGISTER_FORMAT_HALF4.
+	If the <c><i>blendInfo</i></c> structure has an active blend or non-trivial mask when using
+	unsupported output register format, the error code #SCE_GXM_ERROR_UNSUPPORTED
+	will be returned.
+
+	The parameter <c><i>vertexProgram</i></c> is only required to remap texture coordinates.  If all
+	vertex programs that will be used with this fragment program write a contiguous range of
+	texture coordinates starting at <c>TEXCOORD0</c> (or do not write texture coordinates), then the
+	<c><i>vertexProgram</i></c> parameter may be <c>NULL</c>.  Any vertex program that uses texture coordinates
+	that either start at a non-zero binding (such as <c>TEXCOORD1</c>) or form a non-contiguous range
+	must be explicitly linked by passing the program as the <c><i>vertexProgram</i></c> parameter.
+
+	The parameter <c><i>texcoordMap</i></c> can provide an explicit remapping of texture coordinates.
+
+	@param[in,out]	shaderPatcher			A pointer to the shader patcher.
+	@param[in]		programId				The ID for a program registered with this shader patcher.
+	@param[in]		outputFormat			The format for the fragment program <c>COLOR0</c> output.
+	@param[in]		multisampleMode			The multisample mode.
+	@param[in]		blendInfo				A pointer to the blend info structure or <c>NULL</c>. This
+											structure is copied by the function and therefore does not need to
+											persist after the call.
+	@param[in]		vertexProgram			A pointer to the vertex program or <c>NULL</c>. This
+											structure does not need to persist after the call.
+	@param[in]		texcoordMap				A pointer to explicit remapping of texture coordinates or <c>NULL</c>.
+	@param[out]		fragmentProgram			A pointer to storage for a fragment program pointer.
+
+	@retval
+	SCE_OK The operation was successful.
+	@retval
+	SCE_GXM_ERROR_UNSUPPORTED Blending or masking is enabled for an unsupported
+	output register format.
+	@retval
+	SCE_GXM_ERROR_INVALID_POINTER The operation failed because one or more of the pointers supplied was <c>NULL</c>.
+	@retval
+	SCE_GXM_ERROR_INVALID_VALUE The operation failed due to an invalid input parameter.
+	@retval
+	SCE_GXM_ERROR_INVALID_ALIGNMENT The operation failed because some allocated memory did not have the required alignment.
+	@retval
+	SCE_GXM_ERROR_OUT_OF_HOST_MEMORY The operation failed because a host memory allocation failed.
+	@retval
+	SCE_GXM_ERROR_OUT_OF_FRAGMENT_USSE_MEMORY The operation failed because a fragment USSE memory allocation failed.
