Joshua Bell	46e413f3f1	Prevent crashes in Calculator/Eyes DA using ROM FP routines ... During calls, MGTK uses the top half of the zero page to hold the active grafport and local variables. It normally saves/restores the ZP on each call so that the application's ZP state is preserved. Per docs, the ZP1 call with param $00 can be used to disable this; MGTK will write its state to the ZP and assume the ZP is not touched until a subsequent ZP1 call with param $80, allowing higher performance. DeskTop would normally run in this state ($00), except when DAs were invoked since they could use ROM routines (etc) and expect the top half of the ZP to be preserved during MGTK calls. But it did this with a toggle ($00, $80, run the DA, then $00 again). Confusingly, the Calc (and Eyes, c/o copy/pasta) DA would also attempt to get to a normal state when running ($80, run, $00). In rev 30532c31 I disabled DeskTop's toggling around DAs to fix an issue in the Sort Directory DA (see #119), which might have changed the overall behavior. The result is that on the IIc+ (and possibly other hardware, but not Virtual II or Laser 128EX) the Calc and Eyes DAs would crash. This change disables use of the ZP1 by DeskTop and the DAs. This will likely impair performance somewhat due to the save/restore overhead on each call, but at least this gets us to a "known good state". Fixes #157, #158	2019-07-11 15:50:20 -07:00
