string osDrawLine(string drawList, integer startX, integer startY, integer endX, integer endY)

string osDrawLine(string drawList, integer endX, integer endY)

Depending on the form, appends a LineTo drawing command, or MoveTo and LineTo commands, to the string provided in drawList and returns the result.

In the longer form, draws a line using the current pen size and color from to the coordinates indicated by startX and startY to the coordinates indicated by endX and endY.

In the shorter form, draws a line using the current pen size and color from the pen's current position to the coordinates indicated by endX and endY.

After the line is drawn, the pen's X and Y coordinates are set to endX and endY, respectively.
