  38         tags - see below
  39
  40     TAGS
  41         RPTAG_Font (struct TextFont *)  - Font for Text()
  42         RPTAG_APen (UBYTE)              - Primary rendering pen
  43         RPTAG_BPen (UBYTE)              - Secondary rendering pen
  44         RPTAG_DrMd (UBYTE)              - Drawing mode (graphics/rastport.h)
  45         RPTAG_OutlinePen (UBYTE)        - Area Outline pen
  46         RPTAG_WriteMask (ULONG)         - Bit mask for writing
  47
  48         The following tags are compatible with MorphOS (V51) :
  49
  50         RPTAG_FgColor (ULONG)           - Primary rendering color in A8R8G8B8
  51                                           format. Only working on
  52                                           hicolor/truecolor bitmaps/screens.
  53         RPTAG_BgColor (ULONG)           - Secondary rendering color in
  54                                           A8R8G8B8 format. Only working on
  55                                           hicolor/truecolor bitmaps/screens.
  56         RPTAG_PenMode (BOOL)            - TRUE if traditional pen numbers
  57                                           should be used, FALSE if direct RGB
  58                                           colors should be used. Has no effect
  59                                           on non-RTG displays.
  60
  61         The following tags are compatible with AmigaOSv4 (V51) :
  62
  63         RPTAG_RemapColorFonts (BOOL)    - Automatically remap colorfonts to
  64                                           their color on hicolor/truecolor
  65                                           screens.
  66
  67         AROS-specific extensions
  68
  69         RPTAG_ClipRectangle (struct Rectangle *) - Clipping rectangle
  70         RPTAG_ClipRectangleFlags (LONG) - RPCRF_RELRIGHT | RPCRF_RELBOTTOM
  71                                           (see graphics/rpattrs.h)
  72
  73     RESULT
  74         None.
  75
  76     NOTES
  77         Setting one of RPTAG_ClipRectangle or RPTAG_ClipRectangleFlags
  78         allocates internal extra data for the RastPort. After finishing using
  79         this RastPort, you need to manually deallocate the extra data using
  80         FreeVec(rp->RP_Extra).
