Support TeX elements in FreeType renderer.
* libinterp/corefcn/txt-eng.cc: New file. Contains mapping from symbol
name to character code, in Unicode and MS symbol.
* libinterp/corefcn/modules.mk (COREFCN_SRC): Add txt-eng.cc.
* libinterp/corefcn/oct-tex-lexer.ll: Add "\n" to rules applicable to
".", as
the latter does not include new line characters.
* libinterp/corefcn/oct-tex-parser.yy: Remove debug statements.
* libinterp/corefcn/txt-eng.ft.cc (gripe_missing_glyph,
gripe_glyph_render): Change signature from char to FT_ULong.
(ft_render::ft_render): Adapt to new/removed members.
(ft_render::~ft_render): Remove use of fonts member.
(ft_render::set_font): Likewise. Use font instead.
(ft_render::push_new_line): Likewise. Change meaning of yoffset and
initialize line_yoffset.
(ft_render::update_line_bbox): New method.
(ft_render::set_mode): Change meaning of yoffset and initialize
line_yoffset.
(ft_render::process_character): New method.
(ft_render::visit(text_element_string)): Use it.
(ft_render::visit(text_element_list),
ft_render::visit(text_element_subscript),
ft_render::visit(text_element_superscript),
ft_render::visit(text_element_color),
ft_render::visit(text_element_fontsize),
ft_render::visit(text_element_fontname),
ft_render::visit(text_element_fontstyle),
ft_render::visit(text_element_symbol)): New methods.
(ft_render::set_color): Use color member instead of red/green/blue.
* libinterp/corefcn/txt-eng-ft.h (ft_render::visit(text_element_list),
ft_render::visit(text_element_subscript),
ft_render::visit(text_element_superscript),
ft_render::visit(text_element_color),
ft_render::visit(text_element_fontsize),
ft_render::visit(text_element_fontname),
ft_render::visit(text_element_fontstyle),
ft_render::visit(text_element_symbol)): New methods.
(ft_render::update_line_bbox, ft_render::process_character): New
methods.
(ft_render::current_face): Removed method.i
(ft_render::font): New member, replaces obsolete ft_render::fonts.
(ft_render::line_yoffset): New member.
(ft_render::color): New member, replaces obsolete red, green and blue.
(ft_render::ft_font::ft_font()): Implement default constructor.
(ft_render::ft_font::operator=): Fix incorrect use of FT_Reference_Face
return value.
(ft_render::ft_font::is_valid): New method.
* libinterp/corefcn/txt-eng.h (class text_element_symbol, class
text_element_fontname, class text_element_fontsize, class
text_element_fontname, class text_element_fontstyle, class
text_element_color): Add forward definition.
(text_element_symbol::invalid_code): New enum.
(text_element_symbol::code): New member.
(text_element_symbol::text_element_symbol): Initialize it.
(text_element_symbol::get_symbol_code): New method.
(text_element_fontstyle::get_fontstyle): New method.
(text_element_fontname::get_fontname): Renamed from fontname.
(text_element_fontsize::get_fontsize): Renamed from fontsize.
