Albrecht Schlosser 6e407cb169 Fix Cairo drawing in test/cairo_test demo for Windows (#694)
On the Windows platform Cairo drawings must be flushed explicitly.
This is done in Fl_Cairo_Window after calling the draw callback but
it was neither done nor documented in test/cairo_test.cxx when using
another type of Window with its overloaded draw() method, i.e. when
FLTK was configured with --enable-cairoext or CMake OPTION_CAIROEXT.

Note: user code must either explicitly flush the Cairo drawings as
done here or destroy the Cairo context which is not done in this demo
because the Cairo context should be kept alive.

test/README.txt - 20 Oct 1998
-----------------------------

This directory contains tests and demos of FL.  In most cases you can
learn a lot about how to program FL by looking at the source code.

Type "make" to compile them all.

The program "demo" is a graphical interface to run all the demos. (you
may recognize this as a rewrite of an XForms program).

Some of the more interesting programs:

fractals:       A GLUT program with FL controls added to it

glpuzzle:       A GLUT program with no modifications

fullscreen:     Demo of how to make your window toggle to fill screen

list_visuals:   necessary to debug X visual stuff

mandelbrot:     A true application, using panels built in Fluid

menubar:        Demo of how FL's menus work

shiny:          Demo of drawing FL's controls using OpenGL

forms:          An XForms program to demonstrate emulation

colbrowser:     Another XForms program that is actually useful
