this method got overcomplicated, so here's a quick summary
SkinnedObjectDrawTask takes (as it's final argument) pointer to
scene, which is a StackAllocator, so it can allocate a variable-lenght
arrays for matrix-pallete and meshes pointers. Later one these arrays
are being filled:
matrix-palette indirectly, via pose pointer, and
meshes-array via setGeometryAt(index, pointer to geometry)
Sorry for all complications, I couldn't figure out a cleaner solution
for custom allocation.
