0.17.0 to 0.18.0: * Added instances of the affine operation classes (Scale, Rotate ...) for Primitives (path, text label, ellipse). * Added some picture composition functions to Core.Picture. These are useful for testing where the type class complications of Extra.PictureLanguage are an overhead. * Added iRGB to Core.Colour - create RGB colours with integer components [0..255] - and iHSB, iGrey. * Added some test modules for the affine transformations. These illustrate a quirk in Wumpus where, under affine transformation, Pictures may generate a larger bounding box than composite primitives. * Minor change - ztextlabal changed to use 24pt type rather than 12pt. * Corrected the cabal file to include the correct files for the manual. The Haskell source file @WorldFrame.hs@ was missing with the generated file @WorldFrame.eps@ incorrectly included instead. 0.16.0 to 0.17.0: * Added Core.WumpusTypes to export opaque versions of datatypes from Core.PictureInternal. This should make the Haddock documentation more cohesive. * Moved the Core.PictureLanguage module into the Extra namespace (Extra.PictureLanguage). This module may change in detail, if not in spirit in the future as I'm not very happy with it. Also this module is somewhat \"higher-level\" than the modules in wumpus-core, so a different home seems fitting. * Removed CardinalPoint and boundaryPoint from BoundingBox. * Argument order of 'textlabel' and 'ztextlabel' changed so that Point2 is the last argument. * PathSegment constructor names changed - this is an internal change as the constructors are not exported. * Primitive type changed - moved Ellipse properties into PrimEllipse type - internal change. * Removed dependency on \'old-time\'. 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).
