smin
Minimum absolute strength of vector that may be displayed using ggAddVectors()
smax
Maximum absolute strength of vector that may be displayed using ggAddVectors()
Description
The routine ggEnqVectorLimits() returns the minimum and maximum absolute vector strength that may be drawn by subsequent calls to ggAddVectors() as set by ggSetVectorLimits().
If smin and smax are equal then clipping is switched off and all vectors with strength not equal to zero are drawn. The routine ggRestoreVectorSettings() also switches clipping off.
