7b070bbef8 SDL/OPENGL: Add ability to switch between SDL and OpenGL graphics managers. 
OSystem_SDL will create a merged list of all graphics modes from SDL and OpenGL. When the user changes the graphics mode in options and restarts ScummVM should switch to that graphics mode in the corresponding graphics manager.

9daa1c7f93 OSYSTEM: Add resetGraphicsScale() method. 
This fixes a hack for resetting the graphics scale to x1 when starting games that have a large screen size. The SDL graphics manager should now scale back to x1 without changing the current scaler in use, as well as the OpenGL graphics manager.

37f7748a4a OPENGL: Fix crash on Broken Sword 2 when refreshing screen. 
I must admit that I do not know why it does crash, but it seems that updating row by row is safer and does not makes problems.

2636ac4f36 OPENGL: Implement aspect ratio support and toggling. Improve fullscreen switching. Fix cursor scaling bug. 
Now the hotkey Ctrl-Alt-Enter will switch between all available fullscreen modes. Alt-Enter will only switch to the best mode available, and exit fullscreen mode if already on it.
The different aspect ratios can be switched with Ctrl-Alt-A. The normal mode will stretch the contents to the screen, while other modes will stretch only one dimension to the screen size, and maintain the aspect ratio for the other dimension.

b89412d7e4 OPENGL: Redesign blitting system. Add basics for aspect correction. 
Removed the extra surface in GLTexture. Now there are copies of the texture data in their original format (so engine can get the original data when lockScreen or grabOverlay is called). This copies will be updated when the engine calls a function that modifies the game screen/overlay, and the textures will be marked as dirty. When updating screen, the textures will be updated from the copies data if they are dirty.

5b626533cd Change CHECK_GL_ERROR to not take a 'call statement' as parameter 
Passing a 'call statement' to CHECK_GL_ERROR has various issues.
For once, it confuses code parsers in many editors and other
tools that work with C++ source directly.
Moreover, this can lead to subtle bugs if a mistake is
made with the definition of CHECK_GL_ERROR.
It also causes incorrect warnings if CHECK_GL_ERROR is
used with an "empty" call statement.
