Summary0026732: Visualization, TKOpenGl - add option to request Core profile 3.2+ using GLX
DescriptionOpenGl_Window supports creation of core profile only using WinAPI and Cocoa. The GLX should be supported as well for testing within Draw Harness.
Steps To ReproduceN/A
Additional information
and documentation updates		Aspect_Window interface has been extended by new method NativeFBConfig() which should be provided by implementations.

Xw_Window now takes additional argument GLXFBConfig.
    
OpenGl_Window now will not create child window when XVisual for passed window is incomplete for OpenGL context. This should eliminate event-handling issues caused by unexpected window, but would require window to be properly created for OpenGL usage.
TagsNo tags attached.
Test case numberNot needed

 Context created without Core Profile option (Mesa drivers on Linux):
Draw[4]> vglinfo
OpenGL info:
  GLvendor    = 'X.Org'
  GLdevice    = 'Gallium 0.4 on AMD HAWAII'
  GLversion   = '3.0 Mesa 10.5.9'
  GLSLversion = '1.30'


Context created with Core Profile and Debug options:
Draw[7]> vglinfo
OpenGL info:
  GLvendor    = 'X.Org'
  GLdevice    = 'Gallium 0.4 on AMD HAWAII'
  GLversion   = '3.3 (Core Profile) Mesa 10.5.9'
  GLSLversion = '3.30'
  GLdebug     =  ON


Note that Mesa 10.5.9 does not cope with Ray-Tracing program, causing internal exception in the driver:
Draw[11]> vraytrace 1
