Bitmap-data helper modules

Overview:

The modules documented on this page are helpers for fontTools.ttLib that implement lower-level support for various table converters that need to interact with bitmapped data. The BitmapGlyphMetrics module is used for the EBDT/EBLC and CBDT/CBLC tables, and sbixGlyph and sbixStrike are used for the sbix table.
