wxWidgets/include/wx/gdicmn.h
Vadim Zeitlin 0e1f8ea4a3 Remove wxMGL port. 
The company behind MGL toolkit (SciTech) doesn't exist since several years and
this port is not used by anybody, so remove it to ease maintenance burden.

/* Stock objects
wxStockGDI creates the stock GDI objects on demand. Pointers to the
created objects are stored in the ms_stockObject array, which is indexed
by the Item enum values. Platorm-specific fonts can be created by
implementing a derived class with an override for the GetFont function.
wxStockGDI operates as a singleton, accessed through the ms_instance
pointer. By default this pointer is set to an instance of wxStockGDI.
A derived class must arrange to set this pointer to an instance of itself.
