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).
