annotate engine/core/video/opengl/renderbackendopengl.cpp @ 642:6e2151325017

* Added the ability to query the current running screen mode * Added a method to detect the closest supported screen mode (not complete yet). If no matching screen modes are detected an exception is thrown. * Small change to the way the screen is initialized. The screen mode now MUST be in the supported screen mode list before the screen will initialize.
