Helper routines to construct arbitrary compressed strings. These mirror the compression code in snappy.cc, but are copied here so that we can bypass s

A derived class might not need to override this although they can. (but they will probably need to specialize SetTabAreaHeight)

Returns true iff we have hit the end of the input without an error.

AddIcon (with a couple of overloaded versions)

Real CAtlArray: void RemoveAt( size_t iElement, size_t nCount = 1 );

AddBitmap (with a couple of overloaded versions)

Any hash function will produce a valid compressed bitstream, but a good hash function reduces the number of collisions and thus yields better compress
