Detailed Description

a photo of a single char from a font

A char photo is the photo of one character from a font. It is a photo, so it can be drawn. Temporary char_photo objects are used by text to draw a text in a specified front.

Unless you want to drawn characters in a way that is not provided by text it is unlikely that you will ever use this class.

A char_photo contains a reference to its font object. Using a char_photo object when the font object is no longer available will cause unpredictable results. When used with an inline_font, which is a global const (readonly) object, so it can not become unavailable
