# Most glyphs we want to maximize (individually) during the scale
# However, there are some that need to be small or stay relative in
# size to each other.
# The glyph-specific behavior can be given as ScaleRules in the patch-set.
#
# ScaleRules can contain two different kind of rules (possibly in parallel):
# - ScaleGlyph:
# Here one specific glyph is used as 'scale blueprint'. Other glyphs are
# scaled by the same factor as this glyph. This is useful if you have one
# 'biggest' glyph and all others should stay relatively in size.
# Shifting in addition to scaling can be selected too (see below).
# - ScaleGroups:
# Here you specify a group of glyphs that should be handled together
# with the same scaling and shifting. The basis for it is a 'combined
# bounding box' of all glyphs in that group. All glyphs are handled as
# if they fill that combined bounding box.
#
# The ScaleGlyph method: You set 'ScaleGlyph' to the unicode of the reference glyph.
# Note that there can be only one per patch-set.
# Additionally you set 'GlyphsToScale' that contains all the glyphs that shall be
# handled (scaled) like the reference glyph.
# It is a List of: ((glyph code) or (tuple of two glyph codes that form a closed range))
# 'GlyphsToScale': [
# 0x0100, 0x0300, 0x0400, # The single glyphs 0x0100, 0x0300, and 0x0400
# (0x0200, 0x0210), # All glyphs 0x0200 to 0x0210 including both 0x0200 and 0x0210
# ]}
# If you want to not only scale but also shift as the refenerce glyph you give the
# data as 'GlyphsToScale+'. Note that only one set is used and the plus version is preferred.
#
# For the ScaleGroup method you define any number groups of glyphs and each group is
# handled separately. The combined bounding box of all glyphs in the group is determined
# and based on that the scale and shift for all the glyphs in the group.
# You define the groups as value of 'ScaleGroups'.
# It is a List of: ((lists of glyph codes) or (ranges of glyph codes))
# 'ScaleGroups': [
# [0x0100, 0x0300, 0x0400], # One group consists of glyphs 0x0100, 0x0300, and 0x0400
# range(0x0200, 0x0210 + 1), # Another group contains glyphs 0x0200 to 0x0210 incl.
#
# Note the subtle differences: tuple vs. range; closed vs open range; etc
# See prepareScaleRules() for some more details.
# For historic reasons ScaleGroups is sometimes called 'new method' and ScaleGlyph 'old'.
# The codepoints mentioned here are symbol-font-codepoints.
