Removing leptonica dependency from tesseract

[Harsha Jayaweera]

I'm planning to port tesseract ocr to javascript using emscripten.

So to make it more less complex i want to remove leptonica dependency from Tesseract before build it.

In my knowledge tesseract uses leptonica for prepossessing(program by user). Not for any internal/core operations.

So guess i won't need it if i'm gonna use some other library for prepossessing like opencv.

Is this possible.

Am i correct about above idea.

Can i remove leptonica form tesseract-ocr and use it separately.
