I really hope I'm in the right area here.

The drawLine and drawPolygon commands were very nice additions, although it would be very nice to have some parameters available to customize the ui-item.

For Lines:

• thickness,
• style (line, dotted,cut-lines etc) or texture

For Polygons:

• Border Thickness
• Texture / Fill (as currently available in drawRectangle command).

Would be nice in sense of uniformity of the draw-command-family and also help to make great looking UI's easily.
