add specific checks for PangoX and glX. add drawing method using freetype

* configure.in: add specific checks for PangoX and glX.
* src/vteft2.c, src/vteft2.h: add drawing method using freetype and GdkRGB.
* src/vteglyph.c, src/vteglyph.h: add.
* src/vtepangox.c, src/vtepangox.h: add drawing method using PangoX.
* src/vtergb.c, src/vtergb.h: add.
* src/vtegl.c, src/vtegl.h: add placeholder drawing method using freetype and
	glX.
* src/Makefile.am: add newly-added source files to libvte.la target.
* src/vtedraw.c, src/vtedraw.h: add get_visual and get_colormap methods so that
	drawing methods can override the default visual and colormap.  Rename
	get_text_base() to get_text_ascent(), which is more correct.  Remove
	scroll(), which would just wrap gdk_window_scroll().
* src/vte.c: fix logic for choosing alternate render methods when VTE_USE_XFT
	is "0".
* src/vteapp.c: add -- option to stop parsing options with getopt.
* src/vtefc.c: fix incorrect DPI read due to type mismatch (#109513).
