Since this is the first cairo example in the examples directory,
it necessarily involved changes to the Makefile and to fltk-config
to properly handle the absence/existance of the cairo libs.
TBD: Add docs to the cario widget describing coordinate system
and how it differs from the default cairo normalized coordinate system.
opengl apps were left out of the targets list on purpose
so that only non-opengl apps would build.
TODO: Determine a way to detect the presence of fltk opengl libs
from within the Makefile using only fltk-config, so as to
conditionally build the opengl examples.
Do NOT use fltk's own build system (../makeinclude or cmake)
to determine this, so the Makefiles will work as user examples.
