Issue description

After updating to the latest raylib master, GetGestureDetected() no longer returns GESTURE_NONE in any situation. I believe this may be because the touch point count is now updated before calling ProcessGestureEvent instead of after it (changed in this commit). This may lead to the gesture having zero touch points, which there is no handling case for in rgestures.h.

Environment

• Platform / OS: Android 10
• OpenGL version: OpenGL ES 3.2 V@415.0

I have double-checked, and moving the block that updates the touch point count back to after the ProcessGestureEvent call does indeed cause the gesture system to report GESTURE_NONE again. However, perhaps the root cause of the problem is the lack of code in rgestures.h to handle the case of zero touch points. I'm not totally sure how it is meant to behave.
