- getParam now supports synonyms - Renamed "dropLength" URL param to "raindropLength", keeping around support for dropLength URL param - Renamed "texture" to "fontTexture" - Changed "isSlanted" boolean to "slant" angle, adding slant/angle URL param, converted from degrees to radians - Renamed "numGlyphColumns" to "numFontColumns" - Renamed "showRTT" to "showComputationTexture" - Random glyphs are now based on a simple sine scramble - Renaming "now" and "delta" to "time" and "deltaTime" - glyphCycleSpeed is no longer premultiplied; it is now a number between 0 and 1, much easier to visualize
