Fix inverted colors when printing uint8/uint16 images (bug #42107).
* gl2ps-renderer.cc (draw_pixels): Convert the data type to GL_FLOAT, and
divide by the maximum data type value so that range is [0,1].
* gl2ps-renderer.cc (glps_renderer::draw_pixels): Convert and normalize
uint8/uint16 inputs to GL_FLOAT by calling draw_pixels().
