Detailed Description

A Glyph represents one character glyph in the layout.

It contains the index of the glyph within the font and the Quad defining the 3D quadrilateral onto which the glyph is mapped.

math::Vector2f ion::text::Layout::Glyph::offset

Offset from text insertion point to glyph bounds' lower left corner.

For example a '1' glyph often has a positive x offset to keep it from appearing too tight relative to surrounding glyphs, and glyphs with descenders like 'g', 'j', etc. will have a negative y offset.
