  Description
  ~~~~~~~~~~~
  superviewsupport.library contains functions, which are heavily used
  by the superview.library and its SVObjects, SVDrivers and SVOperators.

  superviewsupport.library helps saving diskspace by just holding this
  functions for usage by the other libraries.


  There are also functions, which just might be useful for testing
  and debugging new modules or programs using superview.library.


  superviewsupport.library is mostly independent of the other Libraries yet.
  Nevertheless some of the functions also depend on other Libraries,
  like e.g. SVSUP_DisplayGfxBuffer(), which does SVDriver calls.

  History
  ~~~~~~~
  V6.5 (6.5.1995) :

   - slightly revised memory routines

  V6.4 (30.4.1995) :

   - fully recompiled with SAS/C V6.55
   - now saves A1 when opened/closed
   - prepared to safely handle conversion of GfxBuffers > V2
     (same problem, which would have caused several obsolete versions
      to produce garbage on copying V2 buffers).
     Will cut the version down to the lowest supported now.

  V6.3 (4.2.1995) :

   - fixed behaviour on library open errors when initializing

  V6.2 (25.1.1995) :

   - there was a bug in the ControlPad functions for modifying and
     adding: if an entry already existed it might have been allocated
     less memory than needed for the new entry (1 Byte).
     This caused an Enforcer-Hit claiming that 16 Bytes had been trashed.
     Usually would have crashed the system.

  V6.1 (13.11.1994) :

   - added seven new functions for VIRTUAL MEMORY handling

  V5.1 (29.10.1994) :

   - added three new functions for ControlPad support,
     as e.g. SVSUP_ModifyControlPad()  (-> Steve Quartly)

  V4.3 (28.09.1994) :

   - WritePixelLine8() sometimes seems to destroy the source buffer.
     Fixed now by using a copy of the corresponding line content.

  V4.2 (05.09.1994) :

   - created a workaround for the same "chunky pixel" bug as this has been
     done with the SVDriver-Release of superview.library 8.2
     (sooner or later guru'ed, if width had not been on byte boundary)

  V4.1 (26.06.1994) :

   - added two new functions for temporary displaying of GfxBuffers
     (e.g. for test-purposes) and one function for free'ing "stand-alone"
     GfxBuffers, which are not related to a SVObject-Handle.
   - fixed some bugs in the documentation, concerning the return values
     of the OnePlane/BitPlane-functions (not boolean, but SVERR_)
     and of SVSUP_AllocMemEntry()

  V3.1 (27.05.1994) :

   - added two new functions for converting ONEPLANE SV_GfxBuffers into
     BITPLANE SV_GfxBuffers and vice versa. Works with upto 8 Bit.
     (see SVSupport_Reference.doc)
   - added two new functions for converting Screens into ONEPLANE or
     BITPLANE SV_GfxBuffers. Works with upto 8 Bit.
     (see SVSupport_Reference.doc)

  V2.1 (22.05.1994) :

   - added four new functions for handling new, standardized "ControlPads"
     (see SVSupport_Reference.doc and ControlPad.doc)

  V1.1 (07.05.1994) :

   - first version with 13 functions yet (see SVSupport_Reference.doc)
