* include/hbgtinfo.ch
     + Added comment to compatibility #defines, to not use 
       them, since they deprecated.
       [TOMERGE RC1]
     * HB_GTI_CB_* -> HB_GTE_* (stands for GT Event). Removed 
       plain GTI_ versions, GTI_* range is frozen, pls don't 
       and new codes to them and especially don't use them in 
       core code.

   * include/hbgfx.ch
   * include/hbgfxdef.ch
   * contrib/gtwvg/gtwvg.c
   * source/rtl/gtxwc/gtxwc.c
   * source/rtl/gtwvt/gtwvt.c
     * GFX_* constants renamed to HB_GFX_*. The old ones are 
       still working but it's recommended to update to use HB_GFX_*.
       #define HB_GT_NO_XHB to disable the compatibility #defines, 
       if it collides with your code or you want to test after 
       transition.
     ; [TOMERGE RC1]

   * source/rtl/dirdrive.c
     ! Guarded C53 undoc functions with HB_C52_UNDOC, which is enabled 
       so it won't make a difference in default builds.
     ; [TOMERGE RC1]

   * source/rtl/filesys.c
     ! Fixed hb_fsIsDrv() to use GetDriveTypeA() API, to avoid some 
       win32 system MessageBox() to be shown when certain types of 
       drives (f.e. USB reader devices) are queried.
     ; Please test.
     ; TOFIX: hb_fsChDrv() suffers from the same problem.
     ; [TOMERGE RC1 - after testing]

   * contrib/hbcurl/hbcurl.c
   * contrib/rddads/adsfunc.c
   * contrib/rddads/ads1.c
     % Optimized out explicit function name strings in RTE calls.
     ! The above is actually a fix (I hope) for the one in 
       hb_adsCheckLock(). Error text also made more consistent.
     ; [TOMERGE RC1 - after testing]

   * contrib/hbw32/w32_prn.c
     % Minor optimizations, cleanups.

* NOTE: ACQUIRE / RELEASE screen pair must work same way DispBegin()/DispEnd() pair does

* However, a GT must properly manage its gfx output if the user didn't requested to acquire the
* screen, so this is under user choice.
* (the user just needs to know that it is not the same to aquire the screen, draw 100 lines, then
* release screen, than simply drawing 100 lines -as the GT will be acquiring/releasing the screen
* 100 times, which will slow down things a lot-) [Mauricio]
