BackDrop12 and Wb102

This pair of programs allow you to force Workbench 1.3 to run in
a normal window (as opposed to the backdrop window it usually uses),
and then put up a patterned backdrop window behind it (and all other
windows), similar to the 'desktop pattern' on the Mac and Windows/3.

Having patterned backdrops (as opposed to the blank screen normally 
used) not only looks nicer, but it can make it easier to deal with
lots of windows (gives them something to contrast against).

wb102 is a minimal hack in assembler to force workbench into a 
window - source for Hisoft DevPac v2 assembler is included.
 
backdrop12 allows you to setup a backdrop pattern window, features are
   - user specifiable fill pattern and colour
   - ability to change patterns on the fly
   - support for NTSC/PAL/overscan etc
modula-2 source (for TDI 3.01) is included.
