[M3devel] FW: Win32/ScrollerVBTClass.m3

[Tony Hosking]

Do you mean mentor crashing on Windows?  I would not like us to introduce new bugs to X11-based Trestle by merging Windows with X11 Trestle.

It was not a file replace situation, but rather very careful work trying to merge the changes back into the current tree.  The POSIX implementation did not change, because the modifications were intended for Windows only.  I think it would be wrong to try and make the GUI on Unix look like Windows.

The m3makefiles have been adjusted so that these changes affect only Windows (WIN32) platforms.  These changes were part of work sponsored by Randy Coleburn at Scientific Research Corporation (SRC).  The main files affected are VBTKitEnv.i3, ScrollerVBTClass.m3, and ZChassisVBT.m3, plus some new resource files have been added for WIN32 only.
