Changelog for wumpus-core-0.16.0

0.15.0 to 0.16.0: * Additions to Core.Geometry (direction, pvec, vangle, circularModulo). * Fixed error with langle due to not accounting for circle quadrants in Core.Geometry. * Point2 now derives Ord - so it can be used as a key for Data.Map. * Added escape-character handling to text output in PostScript. This was causing a nasty bug where a drawing would completely fail when special chars shown (GhostView gives little hint of what is wrong when such errors are present). * Changed BoundingBox operation 'corners' to return a 4-tuple rather than a list. * Added centeredAt to PictureLanguage 0.14.0 to 0.15.0: * Added Named colours and "safe fonts" from wumpus-extra. * Added wumpus_core_version to track version number. 0.13.1 to 0.14.0: * Added draft user guide. * Argument order changed for @ellipse@ and @zellispe@ in Wumpus.Core.Picture. * Removed dependency on Data.Aviary. * Removed DList dependency. 0.13.0 to 0.13.1: * Wumpus.Core.SVG changed path_s to path_c - \'S\' was the wrongSVG command to match PostScript\'s @curveto@. 0.12.0 to 0.13.0: * More Haddock documenting. * @lowerLeftUpperRight@ removed from "Wumpus.Core.BoundingBox". * Added range checking and Ord obligation t to the @bbox@ \'smart\' constructor. * Numeric instances for "Wumpus.Core.Colour" improved. * MatrixMult type class simplified * Dash Pattern made a list of on-off pairs rather than just a list * The modules - Wumpus.Core.PictureInternal, Wumpus.Core.PostScript, Wumpus.Core.SVG & Wumpus.Core.Utils - are no longer exposed. * Various operators in "Wumpus.Core.PictureLanguage" changed. * Wumpus.Core.TextEncoding split into an internal and a public module (internal - Wumpus.Core.TextEncodingInternal, public - Wumpus.Core.TextEncoder).
