gfxroute-0.2
--------------

---

'gfxroute' allows to control 'AllocBitMap()' and 'AllocRaster()' of
'fscreen' and/or 'cyberbugfix' so that old programs who require to
put their planes into chip memory will work again on a patched system.

---

NEWS:

    [04-Jul-2008]   0.2     rewritten to be smaller and faster and nicer.
                            removed 'gfxrouteauto' since such "auto"
                            functionality is now integrated in 'gfxroute'.
                            output looks like in 'patchdet'.
    [09-Dec-2007]   0.1-1   small fixes, there was a risk of deallocating
                            memory twice in 'gfxrouteauto'.

---

NOTES:

Requires 68000+(noFPU), OS 3.x, 4+ KiB of free memory, SaferPatches, CGFX
(CGX-AGA,CyberBugfiX) v3 or v4, fscreen 0.21

Toggling these patches seems to be quite safe, havent noticed problems
so far, but if you find something dont hesitate and email me.

Child process can be aborted with Control-C.

If you use 'SystemPatch' then add '-Raster' to its command line or else
disabling AllocRaster() of 'CGFX' will be pointless.

If you use 'Fblit' own AllocBitMap() then disable it completly.

Example programs that require these tools and what to exclude:
 - 'Karate'(demo maker)                      - bitmap
 - 'X'(XFree for the Amiga with driver 2.0)  - raster
 - 'DigiBooster'(tracker)                    - bitmap
 - some other old proggies

Why 'cyber' is here? I found that switching off only 'fscreen's
AllocBitMap() causes bobs to be displayed improperly so by default
AllocBitMap() of CGFX is turned off as well to fix this problem.

This release unlike 0.1 can toggle in both directions, if you specify
'fast' and auto restore then the proggy will turn on the patches and
then switch them off. Auto restore will be activated after passing
timeout value.

My own configuration files for 'CyberBugFix', 'Fblit' and 'mmu.library'
included.

'CGX-AGA'(the one for 68k) and 'CyberBugFix' can be found here:
   http://dariog.republika.pl/download/cgx-aga.lha
'CGFX' v3 is on Aminet:
   http://aminet.net/biz/p5/cgxv41_r70a.lha
for 'fscreen' go here(alpha):
   http://www.grey13.com/files/fscreen021ntta.zip or
or here(fscreen 0.21ntt - compressed with powerpacker):
   http://aminet.net/docs/help/novahdguide.lha
for 'mulib' go here:
   http://aminet.net/util/libs/MMULib.lha

Dont forget to hack 'SystemPatch', use some bin editor like 'ZapHod',
find 'cybergraphics.library' and turn it into 'cybergraphics!library'.
This is necessary if you want additional graphics patches to be
applied(more speed) along with the CGFX subsystem running!

This proggy can sit in scripts even if system does not met required
dependencies.

USAGE:

 *** template: gfxroute <[raster][+bitmap[-cyber]]/s> [chip|fast/s] [timeout/n]

               raster  -  controls AllocRaster() of CGFX
               bitmap  -  controls AllocBitMap() of fscreen
               cyber   -  controls AllocBitMap() of CGFX                                    

               chip    -  use chip memory for planes(switch off patches)
               fast    -  use fast memory for planes(turn them on, def.)

               timeout -  specify timeout for auto restoration

---

EXAMPLE:

   gfxroute bitmap chip 10       ; block patch & wait 10 seconds for the screen
   karate s=demo.txt w=320 h=240 ; screen opens = 'gfxroute' restores patch,
                                 ; note that more time may be required in case
                                 ; of requester.
