[private]

EFLargeNumber = KMaxTInt / 3
EFFontHeightIncreaseFactor = 7
EFMinimumLineDescent = 3
EFBaseLinePosition = 82

EFHeightForFormattingAllText = EFLargeNumber
EFBodyWidthForNoWrapping = EFLargeNumber

Flags used when converting between layout coordinates and document position. CTextLayout::XyPosToDocPosL() CTextLayout::DocPosToXyPosL()

EFIndividualChars = 0	Count individual characters and don't treat the end of the line specially. 6.2
EFWholeLinesOnly = 1	Only consider the beginnings and ends of whole lines. Only useful in XyToDocPos functions.
EFWholeTBoxesOnly = EFWholeLinesOnly	Only consider the beginnings and ends of whole TBoxs so as not to access the document. Only useful in XyToDocPos functions.
EFDisambiguateEndOfLine = 2	Disambiguate the end position of a line from the start position of the next line. If both positions are the same, a position at the end of the line will be invalid, and the position before will be returned instead.

Format modes.

EFScreenMode	Dimensions stored in pixels with no mapping between format and image device.
EFPrintMode	Dimensions stored in twips with no mapping.
EFPrintPreviewMode	Dimensions stored in twips with partial mapping.
EFWysiwygMode	Dimensions stored in twips with full mapping.
