X11: compile `GLXWorkstation` with OpenGL
OpenGL compiler and linker flags are configured locally in
`Make.proto` rather than in target config - this moves the
configuration closer to the code.
Currently all supported (and considered) platforms have OpenGL
implementation. Later on one may use conditionals in makefile
to deal exceptions.

This will replace the viewBackground color.
Instances of me (and subclasses) can be set as a widget's
viewBackground, and will get
fillRectangleX:x y:y width:w height:h in:aView
messages whenever the widget wants to redraw (parts of) its background.
See the example in GradientBackground.
