GetStyleFromSubStyle

[Neil Hodgson]

Another substyles API has been added, GetStyleFromSubStyle along with a corresponding ILexer method, StyleFromSubStyle. This should make it easier for applications to consider all substyles of a particular style equivalent to that style. For example, an application may treat all identifiers as equivalent for spell-checking even though some are coloured differently.

Since substyles is a provisional feature, the version number of the interface was not increased. Lexers implementing ILexerWithSubStyles will need to add the new method. There is a BaseStyle method on the SubStyles class that can be used for this.

I did want to finalise the ILexerWithSubStyles interface for the next version but more functions may be needed by client code.

Another API, GetPrimaryStyleFromStyle, added to convert from a secondary style (such as the cpp lexer's inactive styles) to a primary style.

This helps with substyles. While the distance between secondary and primary styles is always a constant (found through DistanceToSecondaryStyles), the style numbers allocated to substyles may not be next to normal styles or other substyles. This makes it more difficult to determine whether a style number is secondary or primary.
