Add missing include statements, add missing "static" qualifiers or
remove functions which are not used at all.

On most systems float is the IEEE 754 single-precision binary
floating-point format (32 bits). Tesseract does not support other systems.

Remove unneeded include statements, remove conditional statements and
replace the remaining assert.h by their standard C++ variant cassert.

Check whether the top right point of the block is inside of the
thresholded image t_pix. Otherwise the following code would make
illegal memory accesses.

This fixes a compiler warning:
warning: ‘tesseract::TabFind::v_it_’ will be initialized after [-Wreorder]
warning: ‘ICOORD tesseract::TabFind::image_origin_’ [-Wreorder]

It's still possible to set the warning level in the project settings,
but single source files should normally not disable compiler warnings.
