//! Transform and utility tools (rotate/reflect/scale/shear, free transform, eyedropper, gradient,
|
|
//! artboard, magic wand, lasso, measure).
|
|
//!
|
|
//! Like every tool they only emit actions: transforms preview `object.transform` / `object.distort`
|
|
//! on the interaction snapshot, the utility tools execute selection / paint / artboard commands.
