The 'attributes' struct is now 8 bytes and naturally packed (used to be 9 bytes, artificially packed). 'cell' struct is now 12 bytes, naturally packed (used to be 13 bytes, artificially packed). Furthermore, the glyph is stored as a wchar instead of a char*. This makes it easier (faster) to do glyph lookup when rendering.
