Fixed crash if the input data pitch is larger than the locked texture pitch
fixed gles/gles2 renderer creation fail on Android when default major/minor version doesn't match
Fixes #2308, recreate window if GL requirements for the renderer are not met

If the window has been created with values for SDL_GL_CONTEXT_PROFILE_MASK,
SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION not matching those
required by the renderer, attempt to recreate the window.
This is needed on platforms where both GL and GLES 1/2 surfaces are supported
by the video backend, requiring that the window be recreated when switching
between context types.
Mac: Immediately update current OpenGL context's shape.

Previously we were postponing our -[NSOpenGLContext update] call to the next
SDL_GL_SwapWindow, even if the context was current on the current thread. This
changes it so that we will do the update immediately if it's the current
context.

If you're rendering on another thread, you need to call SDL_GL_SwapWindow once
after a resize event to ensure your drawable will produce non-garbage data.

Mac: Fix error message for haptic subsystem.

We were calling SDL_Error instead of SDL_SetError when the haptic subsystem
wasn't initialized.
Mac: Improve moving relative mode windows.

This makes it possible to move windows by their title bar, even if they're in
relative mode, if you click the title bar when the window does not have focus.
