allocatePointer method
Allocates a native slot of count elements in temp under key and
returns the resulting pointer.
Implementations should simply delegate to the appropriate
temp.<Type>(key, count) call. The returned memory is zeroed (or reused) but not
yet populated, call allocateInto or writeInto to fill it.
Implementation
@override
Pointer<ModelAnimationC> allocatePointer(RaylibTemp temp, String key, [int count = 1])
=> temp.ModelAnimation$.At(key, count);
