Question:
Why do line drawing methods like MoveTo and LineTo always
draw a pixel short?

Answer:
This is the way most graphics systems work, including Windows.
The VCL simply maps calls to the GDI functions. If you need a given
line to go all the way to the last coordinate, then simply add one
pixel.
