Static text background color question
This code is dangerous. For example, it does a ::CreateSolidBrush on
EVERY OnCtlColor call, but NEVER deletes it! This will leak brushes
all over the place, and eventually you will consume even NT's massive
GDI space! Instead, create the brush once when the class is
constructed and delete it in the destructor (this gives you one brush
per class instance, which also allows you to have separate colors for
different instances). Just create your own subclass of CStatic and add
a CBrush member variable.
