Now that the GML formatter is both perserving comments and also mostly
agrees to the existing GML style, it can be used to auto-format all the
GML files in the system. This commit does not only contain the scripts
for running the formatting on CI and the pre-commit hook, but also
initially formats all the existing GML files so that the hook is
successfull.
FontPickerWeightModel is no longer necessary as variants contain
weight as part of a complete typeface description. This fixes fonts
not inventorying correctly in picker when they contained more than
bold and regular typefaces. Weight mapping has been moved into
LibGfx/FontStyleMapping.h
This commit adds a SpinBox to the FontPicker dialog to allow users to
set arbitrary font sizes (1 to 255 inclusive) for TTF fonts.
The SpinBox is only visible when the user is selecting a TTF font.
