| 12:11 | tweak: examples some more, more quad/transform down build from debug support. chore: regenerated docs. Leaf check-in: cc9197eeb4 user: aku tags: trunk | |

| 20:48 | chore: regenerated docs. check-in: 82474f828d user: aku tags: trunk | |
| 20:48 | feat: added `transform point` operator to transform single locations. debugging aid. tweak: renamed `transform box` to `transform domain` for clarity. tweak: renamed `quad unit` to `quad unit2`, and `quad quad` to `quad 2quad`. note: examples use `-full`. tweak: `quad 2quad` implementation for clarity. note: main issue in the quad example was a bad order of origin points creating a very twisted transform. note: previous changes, and example changes here all in aid of debugging this. note: issue left now is the forward mapping improperly mapping point C. All else is good. note: unclear if math/equation/implementation error, or even double precision calcs running into limits. note: other quad examples do not show this kind of mis-mapping. check-in: fa7dbe3dfc user: aku tags: trunk | |
| 20:40 | feat: modified helper procs adding dot/line/polyline overlays to images to support multiple colors, and added blue. feat: added `-full` mode for `-matrix` display in examples (no restrictions on float precision in display) tweak: place `-label text under the regular stage description. check-in: 5cfa316912 user: aku tags: trunk | |
