procedure VertLineTSP(X, Y1, Y2: Integer);

Description

Draws a vertical line from (X,Y1) to (X, Y2). The last point is included.

These functions works faster compared to Line. In versions with 'S' postfix necessary clipping to a bitmap coordinate range is provided. In versions without 'S', the Y2 value should be greater or equal to Y1.

VertLineTSP supports line patterns.
