Simulation support:

None. This function is mandatory for all drivers.

Description:

GreDrawLinesInPath draws a sequence of one or more straight lines from the sequence of linked structures addressed by pLine.

This function must be supported by all presentation drivers. However, it is not called by any specific function. GreDrawLinesInPath is used by the filing routines and the path rendering routines within the graphics engine to produce output.
