QuickTime for Windows glue

QuickTime for Windows glue (0x46cca0-0x46d754)

Between the game's code and its support library sits the glue from Apple's QuickTime for Windows 2.x SDK, statically linked (src/zbtools/quicktime.py). It loads QTIM32.DLL (QuickTime) and CMGR32.DLL (its component manager) with LoadLibrary and fetches each one's single _EntryPoint (and _CMgrInitialize/_CMgrTerminate) with GetProcAddress; QTIM32.DLL's file version is read through version.dll. Every API function is a hand-written assembly stub (16-bit register use gives it away) that loads a selector into bx and calls the dispatcher through a pointer: 102 QTIM stubs (13 bytes each, pointer at 0x4a7f84) and 24 CMGR stubs (17 bytes, also setting ax = 1, pointer at 0x4a7f90). Until a DLL is loaded its pointer holds a fallback (0x46ce80, 0x46cca0) that calls QTInitialize and retries; 0x46d3dc is QTInitialize(long *version) and 0x46d745 is QTTerminate().

Nothing maps selectors to API names: QTIM32.DLL exports only _EntryPoint, a few helpers (Flip16, GetMemory, ...) and unnamed ordinals, and the Win16 build imports QTIM.DLL by ordinal. So the stubs are named by selector (qtim_39) until the way the game uses one identifies it. The glue isn't Broderbund's code: the inventory puts it in its own quicktime region, as library code, and uv run ghidra label names it.
