GL window with context.

Must have a parent window (the 'parent' parameter of ctors). The current version inherits TGCanvas (I'm not sure about future versions), probably, in future multiple inheritance will be added - the second base class will be TGLPaintDevice or something like this.

Usage:

Simply create TGLWidget as an embedded widget, and connect your slots to signals you need: HandleExpose, HandleConfigureNotify, etc. In your slots you can use gl API directly - under Win32 TGLWidget switches between threads internally (look TGLPShapeObjEditor for such usage).
You can write your own class, derived from TGLWidget, with PaintGL and InitGL overriden.

Resources (and invariants):

fContainer (TGLWidgetContainer) - controlled by std::auto_ptr
fWindowIndex - controlled manually (see CreateWidget and dtor)
fGLContext - controlled manually (see CreateWidget and dtor)
visual info for X11 version, controlled manually (see CreateGLContainer and dtor)

Exceptions:

can be thrown only during construction.
under win32 class does not throw itself (but some internal operations can throw)
under X11 can throw std::runtime_error (from CreateGLContext).
In case of exceptions resources will be freed.

TGLWidget object is immutable as far as it was created.

Boolean parameter defines, if you want to grab user's input or not. By default you want, but for example when not - see TGLPShapeObjEditor.

Non-copyable.
