It's not a perfect solution because at least on my device internal storage is much faster than sd card. But at least it should be much safer to choose a path with more free space.
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 should depend on features available in graphics drivers and not on headers that were used for compilation.
In theory there was a possible case that GL_VERSION_3_3 was not defined and CVS->getGLSLVersion() >= 330 was true, so that bind wasn't done at all.
And still GL_VERSION_3_3 should be always true for OpenGL renderer because it's defined in glew.
It's not 100% true because GLES has different versions numbering. For example it doesn't have geometry shaders even if they were introduced in GLSL 1.50 (OpenGL 3.2).
But still in this way we make sure that it uses the same features on all devices, no mater if it's GLES 3.0, 3.1, 3.2 etc.
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.
