Initial work on Incline Trails - trails formed from a base vector representing west-to-east but at some angle of incline.
Hopefully arrowheads, some box connectors and path vamps should be derivable from incline trails, so they can all share a library of common primitives.

I've renamed PlacedTrail to AnaTrail - ana indicating anacrusis / prefix. I didn't like the adjectival prefix Placed and AnaTrail matches better with CatTrail.

I've sorted out clock direction for rounding corners, previously it was hacked expecting shapes would be drawn counter-clockwise. Also I've improved the API of the curve trails so they are respective of clock direction, the waveform trails need a similar improvement...

new releases - wumpus
Copperbox revision 2595.
New releases:
wumpus-core-0.52.0
wumpus-basic-0.22.0
wumpus-drawing-0.7.0
wumpus-tree-0.18.0
The changes to Wumpus-Core are cosmetic but important to the higher level layers - renaming clip to clipPrim and changing the types of d2r and r2d. As Wumpus-Core is such a large archive, I've added support for annotating with SVG id attributes to make it a worthwhile Hackage update.

I've added explicit support for SVG id attributes. Text labels support id directly, other elements have only limited support cascading downwards from a SVG group element.
The rationale for this is to support changing text dynamically via DOM scripting, Wumpus is too static to readily support scripting anything else.

I've changed the d2r and r2d functions in Wumpus-Core so that degree is typed to Double rather than a polymorphic a. This means user code can avoid type annotations for the common case where degrees are represented by Doubles.
Copperbox revision 2591.
Updates to Wumpus-Basic and Wumpus-Drawing to work with the Core changes. Also I've stopped exposing jointedAppend from the Path.Base API.

First work towards removing jointedAppend from Paths. I've reworked curved arrowheads to use trails rather than AbsPaths (and jointedAppend).
Also I noticed that the curve CatTrail constructors should account for clockwise and counter-clockwise directions...

I've optimized trail drawing so that contiguous straight lines in the same direction are coalesced. This is potentially useful for drawing Djembe beam groups in Wumpus-Rhythm.
At the weekend, when I've more time to concentrate, I'll look at removing jointedAppend from Paths in Wumpus-Drawing as AbsPaths aren't really monoidal. Also I suspect there are modules in Wumpus-Drawing that use AbsPath when a trail would be better - Arrowheads is one...

I've renamed yesterday's code as the functions were more correctly circle sweeps rather than arcs. The distinction is how they "join" an existing trail - circle sweeps continue round a guiding circle; an arc would be drawn along a possibly tangential vector.
Tomorrow I'll re-implement arcs as they are needed for Wumpus-Drawing.

More work on waveform trails. I've added sine wave and squiggle wave (semicircles) and improved the API so waveforms are drawn according to the number of repetitions - this produces better paths for waves like square or sawtooth that have lines that are otherwise "split" at the end of a phase.

Off-topic, Wumpus's development has slowed down as I'm contracting and have a lot less "free" time. I generally try to do a commit a day, but on days like today the commit can be fairly insubstantial.

I've added a new module Trail for what were previously path schemes or point schemes.
I thought of the name Trail this morning on the lines of breadcrumb trails and the Slint song and it seemed to fit better than path scheme (or PrePath, PathPlan...). Coincidentally, I discovered later that Diagrams has a module Trail for Path like functionality - I follow the Diagrams mailing list, but don't know the library well as I haven't been able to build it on Windows.

I've changed the arg order of the monadic run functions to follow the monadLib style (args then monadic operation) rather than the MTL style (monadic operation then args).
Using the MTL style was as good as forcing code to use where clauses for the monadic operation if they wanted to be typographically neat, whereas the monadLib style can be linear by using ($).
Wumpus-Drawing needs updating to follow this convention.
