Draw_VL ($F3DD)

This routine draws vectors between the set of (y,x) points pointed to by the X register. The number of vectors to draw must already be specified in $C823. The current scale factor is used. The vector list has the following format:

rel y, rel x, rel y, rel x, ...



DP = $D0

X-reg points to the vector list



X-reg points to next byte after list

D-reg trashed
