Modes

Currently, there are several configuration presets with different levels of safety. Normal preset is considered least likely to cause visual errors in the user's environment and is therefore used by default, while the Full one tries to maximize the readability of the rendering for all the font drivers and options, at the cost of severe distortions in the rendering of some elements.
