Graphics functions (device context)
The following routines transmit a handle to a device context and are
particularly associated with the %gr and %dw formats described in (Graphics).
GET_BITMAP_DC@ returns a handle for use with %dw whilst GET_CURRENT_DC@ returns
a handle for a device context created by using %gr. These routines allow
ClearWin+ to be used with Windows API functions and as such are unlikely to be
of interest to a majority of ClearWin+ programmers.
