Implemented my shared world canvas and multitouch-handler library, so now we have canvas pan, individual piece rotation, and (after a lot of effort) cutting of rotated pieces!

The world canvas and multitouch handler were ripped out of #LetterSet into their own libraries, but I had only used their canonical version in #RandomForms, so this was a nice further use. Bonus: all testing for this has been done via my insane iOS-simulator-multitouch-mcp setup!

In the #LetterSet app, I have a library called paper-construction, which is used for creating construction and lined paper. I’m currently working on on on the opposite, paper-destruction, and it is lovely!

@stroughtonsmith I have been working on a “WorldCanvas” library for just this, but it’s taken so much work:
- a multi-gesture handler (for optionally simultaneous pan, zoom, rotate)
- a reusable world, that can translate gestures and position from non-world objects to world objects
- a testing framework for reliably testing both of the above, together

These are all done separately and in use in #RandomForms, but I won’t be confident in their reusability until I upgrade #LetterSet to use them.

Test harnesses beget test harnesses.

This recording shows a new playground I’ve made to test a new “World Canvas” library. The demo encapsulates all of the common UX patterns from #LetterSet and #wishyouwerehere:
- multitouch-handler for simultaneous pan, rotate, zoom
- shape-elasticity for metal effects
- world-canvas for document-based pan / zoom / state
- protocol-based sheets with optional metal rendering.

Garamond has entered the chat in version 1.2.0, just for fun. Entertaining on an iPhone, quasi-useful on an iPad with pencil.

This new version is now live in the App Store, and the font is part of the free version.

LetterSet 1.2.0 is live with all of the good stuff:
- New rulers
- New font (Garamond)
- Higher quality authoring
- More weird interactions (like the very subtle sheet deformations on touch)
- Even a new iPad / macOS gesture for moving a sheet without rotation

And of course, the same arduous design experience... except much faster!

In other news, the upcoming 1.2.0 version of #LetterSet fixes a long-standing, hard-to-track bug regarding complex documents becoming fuzzy over time? I thought maybe it was a scale mismatch or compression issue, but it turns out it was just because I wasn’t explicitly snapping to a pixel grid for each operation! That tiny <0.5px inadvertent rounding step eventually makes the oldest characters look badly compressed. See attached for old/new.

Fixed, finally!

Given all of the recent discussions, I decided to add Garamond into the latest builds of #LetterSet, and it looks good! Cc @gruber et al.
