Commited latest SciTech changes into CVS. This includes updates to the

applet code (with changes copyright headers) as well as updates to the
wxImage and dib.cpp modules to use virtual file systems so that we can
load these objects from ZIP files correctly. The dib.cpp module was
also extensively cleaned up (although the DIB writing code does not
presently use file streams as we couldn't figure out if it was possible
to write to a ZIP file stream). The code has been tested and functions
correctly for both regular files and ZIP files.
