Add option in Tab Grease Pencil

Box deform on Ctrl + T

Example with lattice subdiv and spline deformations.

For details, check this Box deform YouTube demo

How to use: (same tutorial in addon preferences)
Use the shortcut Ctrl + T in available modes
The lattice box is generated facing your view, so be sure to face canvas to avoid unintentional anamorphic offset
Then use the following shortcuts (also displayed in top bar):

Modes and deformation target:

• Object mode : The whole GP object is deformed
• GPencil Edit mode : Deform Selected points
• Gpencil Paint : Deform last Strokes

Shortcuts (also displayed in top bar):

• Spacebar / Enter : Confirm (Combine with Shift to let the lattice in place)
• Delete / Backspace / ctrl+T / Tab(twice) : Cancel
• M : Toggle Linear and Spline mode at any moment
• 1-9 top row number : Shortcut to subdivide box
• Ctrl + arrows-keys : Subdivide the box incrementally in individual X/Y axis

Notes :

If you return in box deform after applying with a ctrl+Z, you need to hit ctrl+T again to revive the modal.

A cancel warning will be displayed the first time you hit Tab (to avoid mis-canceling)

Multiframe edit selection works, but you will only see the current frame during the modal

Shortcut changed are refreshed upon modifications.

There are several settings to customize visual aspect and behavior in addon preferences:

• "Always Snap" checkbox invert the snapping behavior
• Special "Rolling" mode is available. It displays keyframes with a constant spacing, discarding timing data when scrubbing back and forth. This is useful for quick flipping between keyframes.
