Description:
Mac-specific code for initialization & displaying command-line options & output window.
------------------------------------------------------------------------------
Author:
Alexander Enzmann, [70323,2461]
Eduard Schwan, [espsw@compuserve.com]
------------------------------------------------------------------------------
Change History:
9212?? [ae] Created.
921214 [esp] Updated to compile under MPW C as well as Think C.
930117 [esp] Added MacInit, MacMultiTask, MacShutDown, GetOptions code
930317 [esp] Added MoveToMaxDevice, environs check, collapsed multiple
dialogs to 1, changed display_init to accept bg_color
930418 [esp] Added driver checks.
930803 [esp] Changed argv parameters to match new 3.1a format.
930805 [esp] Added radios for the -t/-c output_format switches.
930817 [esp] Added ColorQD check in Display_Init.
930918 [esp] Fixed up logic for input parm prompting.
930918 [esp] Added grody quick fix to redraw please-wait dlg on switchin.
940725 [esp] Removed special palette, use System palette to avoid Finder color snatching
950422 [esp] Changed popup menu handling to simpler System 7-only control style
970421 [esp] Updated to CW11 Universal interfaces
980102 [esp] Fixed argv/argc bug which was stomping on memory, updated to CWC Pro 2
