revamp text rendering classes
* base-text-renderer.h: New file.
* ft-text-renderer.h, ft-text-renderer.cc: New files for freetype text
rendering classes, adapted from txt-eng-ft.h and txt-eng.cc.
* text-renderer.h, text-renderer.cc: New files. Public interface for
text rendering.
* gl-select.cc, gl-render.cc, gl-render.h, gl2ps-print.cc,
graphics.cc, graphics.in.h: Adapt to use new text rendering interface
that does not require checking HAVE_FREETYPE.
* libinterp/corefcn/module.mk: Update.
