debug: cleanup ogl_tex, tex: use full-width types to avoid truncation warnings wdbg_sym.cpp: skip __suppress and __profile symbols; add additional hex display for floats; cleanup wdll_ver.cpp: cppdoc+cleanup (remove non-reentrant C interface, replace with std::string) sysdep: add cppdoc everything else: flag parameters are now consistently size_t instead of int (avoids warnings, allows slightly better code on x64) This was SVN commit r6392.
