- * Font Management
- * The output of a console is a fixed-size table. That is, it consists of many
- * cells where each character is printed either into a single cell or spread
- * across multiple cells. However, there will never be multiple characters in a
- * single cell so cell indexes are the smallest position information.
- * The classic console uses one character per cell. Newer consoles may allow
- * widened characters, though. Common are characters that are double-width and
- * characters that are double-width+double-height.
- * If you mix many different widths/heights then this might get very
- * memory-consuming as we need to have one loaded font for each size to get
- * decent results. Therefore, avoid widths/heights other than the ones
- * mentioned.
- *
- * Therefore, this layer does not provide the classic font APIs, instead it
- * offers a font_screen object which represents the whole screen. You specify
- * the x/y coordinates of your framebuffer/target and the font plus point-size
- * that you want to use. This layer automatically computes the pixel size and
- * resulting row/column counts.
- * For reversed logic you can also specify row/column counts and the API
- * calculates the required font-point-size.
- * In both situations you never have to deal with font related details! The only
- * thing you need to know is the row/column count of the resulting table and
- * all the characters in the table.
- *
- * When drawing a screen you need to tell the font layer where to draw the
- * characters. For performance reasons this is split into several tasks:
- *   1: Start a drawing operation. This resets the screen and prepares the font
- *      for drawing. It clears all previous entries.
- *   2: Add each character you want to draw to the font_screen object with its
- *      cell position and cell width. The width is probably always 1/1 but for
- *      multi-cell characters you can specify other widths/heights.
- *   3: Perform the drawing operation. This instructs the font-layer to actually
- *      draw all the added characters to your surface.
- * You need to perform all 3 steps for every frame you render.
