ENTITY*,STRING* name,VECTOR* scale)
Scales an entity bone, it's childs and all attached vertices in x, y, and z direction.
ENTITY* - entity pointer
name - name
or handle of the bone, STRING* or char*
scale - VECTOR* or var with x, y, z scale factors.
0 if the bone was not found,
This instruction does not set the bone to a certain scale, it rather multiplies
it's current scale by the given factors. For setting the bone to an certain scale,
perform ent_bonereset before. This instruction
can also be used to remove polygons attached to a certain bone by setting its
scale to (0,0,0).
temp.x += time_step;
temp.y = 1;
temp.z = 1;
ent_bonescale(my, "bone", temp);
