  * $Revision V1.07
  * ---------------
  * 1.  Replaced hardwired interrupts with system friendly calls just so I
  *     could get it working on my system! Now the editor is multitasking and
  *     the self-modifying code for the interrupt gone making it work! Hurray!
  * 2.  Reworked scrolling routines a bit for slightly improved refresh rate
  * 3.  Most direct references to 320 pixels hardwired screenwidth replaced
  *     with screen structure access for autosensitivity (screenmode switch)
  * 4.  Replaced old `inbuilt' file-requesters with a new system friendly and
  *     standard 'reqtools' requesters. Now finally we are able to load and
  *     save data to/from hard-disks.
  * 5.  All blit routines now use blit nasty during blitting for a little
  *     extra performance.
  * 6.  Print routines modified to use 7 pixel print width instead of 10
  *     to enable more descriptive text in gadgets and make them look a bit
  *     nicer on the eye.
  * 7.  Screen display copperlist now uses 64-Bit AGA fetchmode`s for some
  *     additional screen refresh speed.
  * 8.  Added a check to the mouse x-scaling factor for when running in high
  *     resolution screen mode so that the the gadget coordinates are correct.
  * 9.  All window x-start positions are now ignored, instead the windows
  *     are now centred on the screen dependent on the screen pixel width.
  *     This feature really should be added as an option to the window flags
  *     but for now I have simply bypassed the window`s xstart regardless.
  *     This is a simple fix to make windows appear in the centre of the screen
  *     for when running in high-resolution mode.
  * 10. Preview scaling now works in high-resolution mode.
  * 11. Moved workbench startup code into its own file for asm-one direct
  *     to support `assemble-run' feature.
  * 12. Code hunks sectioned into public memory, now only graphics data and 
  *     copperlists in chipmem (along with screen buffers). This speeds up
  *     the code a fair bit on my system now that the code is in fast-ram 
  *     and also saves 100k of chipram and lots on filesize.
  * 13. Removed unneccessary button gadget data`s and changed gadgets imagery
  *     to look a little more modern.
  * 14. Minor changes to copper display code to reflect the newlook gadgets.
