🛠️ Update 1.71 - New demo camera, exact stock sizes, FPS mode, and other fixes

This update adds a cinematic "show" camera, a first-person workshop walkaround, smarter G-code, and a long list of fixes. Here's everything that's new.

✨ New

• Show camera (F4) — automatically follows your program and frames the action as it runs. On the lathe it keeps a good angle on the cut and stays clear of the chuck and tool holder.

• First-person mode (F3) — walk around the workshop on foot.

• Cross-machine workpieces — open a part you made on a different machine and keep working on it.

• Quick zero-point buttons — set your program's origin to a corner, edge or center of the stock in one click.

• Automatic tool groups — tools are now organized into groups in the tool list.

• More canned cycles — additional drilling and boring cycles supported in G-code.

• Wider subprogram support — both call formats (M97 local and M98 O-program) now run correctly, whichever style your program uses.

• Example G-code — sample commands shown in the INFO tab to make them easier to learn.

🔧 Improvements

• Workpieces are now made at exactly the size you set.

• The tool-path preview now follows tool changes correctly.

• Smoother freehand drawing — now seamless across chunk edges and works while the lathe is spinning.

• Spinning workpieces on the lathe now look correct at any speed (no more frozen, backwards or stuttering rotation).

• Smaller save files.

🐞 Fixes

• Japanese, Chinese and Korean text now shows correctly (no more squares).

• A tool change (M6) now stops the spindle.

• Cutter radius compensation fixes.

• CNC lathe work offsets fixed.

• Feed rate unit can no longer be changed while a program is running.

• Drilling on the lathe now uses the drill's own diameter for cutting speed instead of the workpiece diameter.

• G-code no longer misreads "X+ 10" as X0.

• Invalid characters in file names are now stripped before saving, so saves no longer fail.

• Better quality on the piece that falls away after a cut-off.

• Camera no longer locks onto the workpiece incorrectly at startup.

• Workshop favorites filter works again.

• Fixed an error when the active CNC tool index had no tool on the changer.

• Fixed cutting breaking (and a crash) after a piece was cut off and the workpiece was re-clamped.

• Various stability fixes.
