Metrics 全世界の to the font, i.e. not 明確な／細部 to 選び出す／独身
glyphs. The font 高さ is defined as
ascent+降下／家系+internalLeading, and therefore not explicitely
含むd here.
Please 公式文書，認める that when querying FontMetrics from an XCanvasFont
interface, all values here are given 親族 to the font 独房
size. That means, the referenceCharWidth and/or
ascent+降下／家系+internalLeading will だいたい (一連の会議、交渉／完成するd to
integer 装置 決意／決議, or 正確に／まさに, if わずかの font
（判決などを）下すing is enabled) match the referenceAdvancement/cellSize
members of the FontRequest for which the XCanvasFont was
queried. Please be aware that the values returned in this
structure only 地図／計画する one-to-one to 装置 pixel, if the 連合させるd
（判決などを）下すing 変形 for text 生産（高） equals the 身元
変形. さもなければ, the text 生産（高） (and thus the resulting
metrics) will be 支配する to that 変形. Depending on the
underlying font 科学（工学）技術, actual 装置 生産（高） might be off by
up to one 装置 pixel from the transformed metrics.
