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. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@10551 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

REMARKS:
|

To create new variables for the #if, #else and #endif HTML preprocessing

blocks you need to derive classes from wxIfElseVariable and override the

pure virtual GetValue function. However this should not be done directly
|
|
but by using the BEGIN_IFELSE_VARIABLE and END_IFELSE_VARIABLE macros
