		std::string::const_iterator	end,
		int	width,

ceildiv()

int Gorgon::Graphics::internal::ceildiv	(	int	v,
		float	f
	)

decode()

Glyph decode	(	std::string::const_iterator &	it,
		std::string::const_iterator	end
	)

Decodes a utf-8 character from the given iterator.

If char is not valid 0xfffd is returned. \r\n is mapped to \n

References Gorgon::end().

defaultspace()

float Gorgon::Graphics::internal::defaultspace	(	Glyph	g,
		const GlyphRenderer &	renderer
	)

References ceildiv(), GlyphRenderer::GetCursorAdvance(), GlyphRenderer::GetDigitWidth(), GlyphRenderer::GetEMSize(), GlyphRenderer::GetMaxWidth(), and rounddiv().

dodefaulttab()

void Gorgon::Graphics::internal::dodefaulttab	(	T_	s,
		T_ &	x,
		T_	w
	)

DrawQuadVertices()

isadjustablespace()

isbreaking()

bool isbreaking

isnewline()

isspace()

rounddiv()

int Gorgon::Graphics::internal::rounddiv	(	int	v,

	)

simplelayout()

void Gorgon::Graphics::internal::simplelayout	(	const GlyphRenderer &	renderer,
		std::string::const_iterator	begin,
		std::string::const_iterator	end,
		std::function< int(Glyph, Glyph)>	spacing,
		std::function< int(Glyph)>	advance,
		std::function< bool(Glyph, int, float)>	process,
		std::function< void()>	dotab,
		std::function< void(Glyph)>	donewline
	)

helps with the simple layouts, decodes and executes unicode instructions.

Offset parameter in render function is the offset that must be used after rendering the character. If g is 0, only offset should be processed. This overload calls process function even for glyphs that are not normally rendered, and allows return value from the layout function to stop processing further.

simpleprint()

void Gorgon::Graphics::internal::simpleprint	(	const GlyphRenderer &	renderer,
