The force legacy device graphics restriction is needed for ironlake graphics cards. But newer generations in pentium/celeron processors also are named just "Intel(R) HD Graphics" without any number.
The newest drivers for ironlake graphics card is 8.15 and it's unlikely that it will get an update. So assume that all drivers older than 9.x are ironlake generation or that are too old to run STK anyway.
It's a bit ugly solution because we should handle it properly in one place and not add another sRGB correction... But it's already working solution and it doesn't affect the OpenGL renderer, so we can use it until better fix will be done.
Now the GLES renderer looks almost the same as the original OpenGL 3.x one :)
It should be much more comfortable on small devices.
Though it's not possible to get default screen orientation (and real device orientation) using NDK functions, so at this stage user has to manually choose if he needs "tablet" or "phone" accelerometer.

It allows to enable it easily in GLES renderer. And we check if this extension is available anyway because it's needed for shadows, so we can use it for other shaders too.
It may be useful if someone wants to play with external keyboard.
The multitouch_mode parameter will be also used to choose between steering with buttons and using accelerometer.
It is generally safe for GLES drivers. The driver often reports OpenGL ES 3.1 or 3.0 support even though we request only GLES 2.0. But we can still use GLES 2.0 / GLSL 1.0 functions on GLES 3.x context, so it shouldn't cause any issues.
I also added Android Emulator to graphics restrictions.
This function was used by Cand for his OpenGL 2.1 renderer. The round function is available since GLSL 1.3 (OpenGL 3.0), so there is no need to override it.
If it will be needed in future, I suggest to change the name to round_stk or something similar.
