Type 2.0

PR for typography module 2.0

There are a number of new functions added to the p5 prototype:

• textBounds: tight bounds, now supported for all fonts, not just those with paths as in v1
• fontBounds: gives the (loose) bounds for the font, regardless of characters used
• fontWidth: gives the (loose) width of a string of given length in the font, regardless of the characters
• textProperty: allows set/get for one of about 20 font-related properties
• textProperties: allows batch set/get for one or more of about 20 font-related properties
• textToPoints: a correct version via typr.js (need to support for path sampling)
• textToPaths: returns a more complex object to allow rendering of paths
• textDirection: exposing this directly for wider access
• textWeight: specifies weight via num (100-900) or keyword, requires support in font (useful with variable fonts)
• fontAscent: gives the ascent for the font itself (the max of any glyph)
• fontDescent: gives the descent for the font itself (the max of any glyph)

Also to be included in p5.Font:

• textToContours
• textToModel

Issues/Questions/Notes:

• Need better examples in arabic and other RTL languages for testing
• To pass a complete css-font-string directly, call textFont() with the string as first argument (which must include family and size, as per HTML5 spec for font shorthand)
