Methods Fl::event_x_pixel() and Fl::event_y_pixel() committed at r.10941
are removed. Instead method Fl_Gl_Window::pixels_per_unit() is added.
The documentation explains in more detail how to write cross-platform
FLTK code supporting high resolution OpenGL windows on retina displays.
The examples/OpenGL3test.cxx app exercises Fl_Gl_Window::pixels_per_unit().

in pixel units that differ from FLTK units for OpenGL windows mapped to a retina display.
On non Mac OS platforms, these are synonyms of Fl::event_x() and Fl::event_y().
The example/OpenGL3test demo program is modified to call these new functions.

On the X11/MSWindows platforms, this requires external installation of the GLEW library.
This fixes STR#3198 and STR#3257.
Added two new examples programs.
