//This table establishes the memory requirements for this font.
//Fonts with CFF data must use Version 0.5 of this table,
//specifying only the numGlyphs field.
//Fonts with TrueType outlines must use Version 1.0 of this table, where all data is required.
//Version 0.5
//Type Name Description
//Fixed version 0x00005000 for version 0.5
// (Note the difference in the representation of a non-zero fractional part, in Fixed numbers.)
//uint16 numGlyphs The number of glyphs in the font.
//Version 1.0
//Type Name Description
//Fixed version 0x00010000 for version 1.0.
//uint16 numGlyphs The number of glyphs in the font.
//uint16 maxPoints Maximum points in a non-composite glyph.
//uint16 maxContours Maximum contours in a non-composite glyph.
//uint16 maxCompositePoints Maximum points in a composite glyph.
//uint16 maxCompositeContours Maximum contours in a composite glyph.
//uint16 maxZones 1 if instructions do not use the twilight zone (Z0), or 2 if instructions do use Z0; should be set to 2 in most cases.
//uint16 maxTwilightPoints Maximum points used in Z0.
//uint16 maxStorage Number of Storage Area locations.
//uint16 maxFunctionDefs Number of FDEFs, equal to the highest function number + 1.
//uint16 maxInstructionDefs Number of IDEFs.
//uint16 maxStackElements Maximum stack depth across Font Program ('fpgm' table), CVT Program('prep' table) and all glyph instructions(in the 'glyf' table).
//uint16 maxSizeOfInstructions Maximum byte count for glyph instructions.
//uint16 maxComponentElements Maximum number of components referenced at “top level” for any composite glyph.
//uint16 maxComponentDepth Maximum levels of recursion; 1 for simple components.
