		int	dst_size,
		const uint8_t *	src,
		int	src_plane_size,
		int	nplanes
	)			[static]

PCX run-length encoder.

Parameters:

	dst	output buffer
	dst_size	size of output buffer
	src	input buffer
	src_plane_size	size of one plane of input buffer in bytes
	nplanes	number of planes in input buffer

Returns:

number of bytes written to dst or -1 on error

Bug:

will not work for nplanes != 1 && bpp != 8
