Summary
Function: integer llScaleByFactor( float scaling_factor );| REQUEST | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Attempts to resize the entire object by scaling_factor, maintaining the size-position ratios of the prims.
Returns a boolean (an integer) TRUE if it succeeds, FALSE if it fails.

Deep Notes
This function is roughly equivalent to the following: <lsl> float VectorAbsStatistics(integer flag, vector a){
return llListStatistics(flag, [llFabs(a.x), llFabs(a.y), llFabs(a.z)]);
}
integer ScaleByFactor(float scale) {
vector root = llGetScale() * scale; if(VectorAbsStatistics(LIST_STAT_MAX, root) > 64
