ACSLogo specifications

On-screen graphics have been brought into line with the graphics produced when exporting to PDF. This means you get proper 'corners' when drawing a connected series of lines, and most of the performance problems which emerged with Leopard should have gone.

New functions have been added - Wrap returns whether wrap is on or off , Shadow returns the shadow state, ColourAtPoint returns the colour of the pixel at the supplied co-ordinate.

You can now export graphics as JPEGs and PNGs as well as TIFFs and a few other types..

The Towards function sometimes gave the wrong angle; this should be fixed. A crash which occurred when opening a tutorial that is already open should be fixed.
