sx,sy,sz
Scale factors for X,Y and Z coordinates respectively
Description
The routines gScale2D() and gScale3D() set independent scale factors for X,Y (and Z) coordinates by modifying the current modelling transformation matrix.
In space mode (the default) this scaling is specified with respect to the current space axes, whilst in picture mode (see gSetTransformMode()) the scaling is specified with respect to the picture axes.
For negative values of sx, sy and sz, the routine mirrors the drawing about the axis by the absolute scale factor sx, sy or sz.
