DrawTarget::draw_text panics if a glyph is not present in the provided font

let id = font.glyph_for_char(c).unwrap();

Presumably we should be drawing a tofu glyph instead?

The draw_text API is mostly a toy. The correct solution to use draw_glyphs with proper glyphs selected for the font. i.e. it's the user's responsibility to only draw glyphs that exist in the font.
