Fix billboard error which used the wrong width for top and bottom width of trapezoid billboards. The reason is the use of cross-product, which flips the vertical axis used in calculations. Properly documented in the code now, API now works as expected. Bug and fix provided by pc0de.

Oops, misread the switch. Alpha representation always requires 32bit, so reverted to original code with just another empty default statement.

Add new normal render method to all places where this is already supported. Thereby replacing some of the old and time consuming normal renders, as pointed out by pc0de

Fix warning about conversion. We might have to do it vice versa, though, comparing the float values and passing a converted number down to getMesh.

Add a FPS setting for animated meshes. This allows to store an overall animation speed for a mesh, which enables reading this information from the formats that support it and set the animation speed in scene nodes accordingly.

Also added a fix for proper update of animated meshes, as suggested by Reiko. This was missing from the recent update of improved selector usage and should now re-enable the proper handling of animated poses in selectors.
