+How the platform abstraction works
+ + InitVCL calls 'CreateSalInstance'
+ + ths is implemented by the compiled-in platform backend
+ + it stores various bits of global state in the
+ 'SalData' (inc/saldatabasic.hxx) structure but:
+ + the SalInstance vtable is the primary outward facing gateway
+ API for platform backends
+ + It is a factory for:
+ SalFrames, SalVirtualDevices, SalPrinters,
+ Timers, the SolarMutexe, Drag&Drop and other
+ objects, as well as the primary event loop wrapper.
