This patch improves the `Text_painter` utility that is commonly used by native Genode components to render text: - Support for subpixel positioning - Generic interface for accessing font data - Basic UTF-8 support Since the change decouples the font format from the 'Text_painter' and changes the API to use the sub-pixel accurate 'Text_painter::Position' type, all users of the utility require an adaptation. Fixes #2716
