and declare it in non-public header src/Fl_Scalable_Graphics_Driver.H which also
declares classes Fl_Font_Descriptor and Fl_Fontdesc.

libXft was erroneously present in the link command when using Pango and Cairo.
This is fixed by disconnecting the GUI scaling code from use of Xft.
This commit also makes sure that when Wayland is used, pkg-config is available
on the build machine. This allows to remove from file CMake/options.cmake
code that was labelled with "FIXME".

The previous approach FLTK used to create OpenGL contexts under the X11 platform
followed a different code path to create contexts for OpenGL version 3 and above
than to create contexts for OpenGL versions 1 or 2.
The FLTK code followed exactly "Tutorial: OpenGL 3.0 Context Creation (GLX)"
of the official OpenGL wiki, see:
https://www.khronos.org/opengl/wiki/Tutorial:_OpenGL_3.0_Context_Creation_(GLX)
That code worked OK with Debian 11 and with any tested Linux configurations
in a VM running on Apple hardware. However, it failed with Debian 12 and later
on native Linux boxes to create GL3 contexts with the FL_DOUBLE flag.
That's what issue #1005 reports.
A first attempt to fix #1005 followed instructions given at:
https://registry.khronos.org/OpenGL-Refpages/gl2.1/xhtml/glXIntro.xml
which supposedly describe how to create OpenGL contexts with GLX.
That had no effect on issue #1005.
This commit erases all attempts to use OpenGL3-specific calls or even
the more modern glXCreateNewContext() function that appears with
GLX version 1.3. The committed code uses only OpenGL 1-age
functions to create OpenGL contexts for X11 windows.
Created contexts follow the "Compatibility Profile" which means they
are compatible with both modern OpenGL3-style and legacy OpenGL1/2-style.
This appears to fix issue #1005.

... "when there's no current window".
Silently ignore GLUT function calls that need a current window if the
current window is NULL, return 0 from functions that return an 'int'.
Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers().
This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise.
Note: the chosen implementation to ignore GLUT calls silently appears
to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error
messages and exit. The latter could be implemented as well but would
be much more work.
