Subject: Use rint() for some more rounding of vertices.

Add fl_parse_color() to X11 version, too, and use it instead of XParseColor
in the image handling code.

Move the default color stuff in the plastic scheme to the MacOS
get_system_colors(), and apply the background color to the tile image.

More fixes for test makefile.
