Question: Re: Hey I didn't know this malloc behavior, that's great. Do you have any suggestions on how large I should alloc the block?

Figure out what the reasonable maximum number of files you'd ever open is, and multiply it by the typical file length (it doesn't store the path per file, thankfully, just path then file list). Comment...

I'd just allocate a big buffer and hope for the best... If you malloc() a large buffer and only write the beginning of it, it won't actually reserve physical RAM for the buffer that is unused, so while it will temporarily waste some address space, it won't actually be using the RAM. Comment...

Question: could you briefly explain the purpose of various LICE_*Bitmaps? thanks

LICE_IBitmap: abstract interface for all lice bitmaps
LICE_MemBitmap: bitmap backed by a malloc()'d buffer
LICE_SysBitmap: bitmap backed by a buffer that also has a HDC associated with it (on OSX, this implies a SWELL HDC). For these, getDC() returns non-NULL.
LICE_SubBitmap: a utility wrapper to have a subimage of another LICE_IBitmap. If you wish to clip drawing to a rectangle, you can use this.
LICE_WrapperBitmap: used if you want to wrap some foreign buffer and make it accessible for LICE functions.
