- Store a rectangle rather than separate origin / end points. This is simpler, and for PR #1515 this will likely be extended further to also store an orientation - Clarify that the bounds are only used for interactive manipulation by tools, and might not reflect the selection's entire bounds when e.g. using intersection modes - Adjust the `TransformPoint()` signature to be easier to use

…of selections - Use the rectangle handle to define how the selected area is scaled - Update the rectangle handle when dragging to translate the selected area Bug: #585

Good feature. Why is this still a WIP? |

I took a run at finishing this checklist in #2239 — it adds handle-follows-rotation and the original-aspect-ratio Shift constraint on top of the scaling/translate handles, plus arrow-key nudge shortcuts and a rotate cursor. Built on your approach here (and @marcovr's branch); happy to fold it into this PR instead if you'd prefer. |

…aProject#585) Completes the checklist from the draft PR PintaProject#1515 by wiring RectangleHandle into BaseTransformTool so the Move Selected/Selection tools expose grips: - Use the rectangle handle to control scaling, anchored to the opposite corner (or edge) instead of the center; Ctrl anchors to the center. - Dragging to translate (mouse or arrow keys) keeps the handles glued to the moved region. - Rotations rotate the handles too: a live orientation matrix maps a fixed reference rect onto the current on-screen quad, and grip drags are mapped back through its inverse so rotated content scales along its own axes with the opposite oriented corner pinned and no shear. - Shift constrains to the content's original aspect ratio rather than to a square. Also draggable corners can flip/mirror the content when pulled past the opposite edge, and holding a modifier over a grip shows a hint. Arrow keys nudge (Shift = 10px, Ctrl = 10% of canvas) with a hint after a short hold (issue PintaProject#1559). Adds a high-contrast bidirectional rotate cursor icon. Credit: cameronwhite (draft PR PintaProject#1515, refactor PR PintaProject#1712) and marcovr (master...marcovr:Pinta:allow-handle-resize) for the handle-resize approach this builds on.
