TGLWidget and TGLContext classes were designed to isolate gl-context/gl-window specific code inside gl module.
Unfortunately, this isolation is bad as soon as we have to work with Obj-C, OpenGL, classes from Cocoa module.
TGLFormat can not go to core/base (because of multi-sampling part of code), I have to convert format into something,
I can pass to gVirtualX - array of pairs (enumerator-value).
