Juan Linietsky 990f6cf50e More Bug Fixes 
-=-=-=-=-=-=-

-Fixed a few bugs in Mixer, now playback of chiptunes works great :)
-Changed how visibility AABB generation from skeletons work, it's fully automatic and real-time now, generated from current skeleton pose for the frame.
-Fixed camera in 3D kinematic character demo.
