wxWidgets/include/wx/gtk1/bitmap.h
Vadim Zeitlin 41b1ba3c9e Replace many identical wxBitmap::CopyFromIcon() with a single one
Define CopyFromIcon() directly in wxBitmapBase for the non-MSW ports, as
it was implemented exactly in the same way in all ports using this class
anyhow.

This means this function is not virtual any longer, but this shouldn't
be a problem as it was never supposed to be overridden in application
code and this couldn't be done with wxMSW, where it never was virtual in
the first place, anyhow.

No real changes, just a simplification.
