Draw_VLcs ($F3D6)

This routine draws vectors between the set of (y,x) points pointed to by the X register. The number of vectors to draw is specified as the first byte in the vector list. The scale factor is specified as the second byte in the vector list. The vector list has the following format:

count, scale, rel y, rel x, rel y, rel x, ...

ENTRY:

DP = $D0

X-reg points to the vector list

EXIT:

X-reg points to next byte after list

D-reg trashed
