Comments

This buffer can be used as an alternative to pixelShadow, allowing you to switch between two text screens.

Several flags affect the use of this buffer:

• When either appTextSave is cleared or textDisplayOnly is set, nothing is drawn to the pixel shadow. For example, appTextSave is normally cleared by the OS when a menu is displayed.
• If putmapUsePixShad2 is cleared, pixelShadow is used instead.
• For variable-width text routines, if write_on_graph is set, the characters are drawn to the graph buffer instead.
