wxWidgets/src/msw/printdlg.cpp
Vadim Zeitlin 9dbf785a99 Work around buggy printer drivers not returning correct DEVMODE size. 
Apparently at least one printer driver doesn't report the memory needed by its
own DEVMODE struct correctly, resulting in a crash due to a buffer overflow
when printing using it.

Work around this by allocating slightly more memory than what we really need.

Closes #16274.
