PLUGIN: Global - Mode switching can accidentally make OP fail

[Danweel]

=needs more testing=

highlights3, frames1, frames2, op14, op8, op12:

has:

bpy.ops.object.mode_set(mode='PAINT_GPENCIL')
# ... do stuff ...
bpy.ops.object.mode_set(mode='EDIT_GPENCIL') _# sometimes_

In THEORY, if you accidentally leave the object in the wrong mode, the next operator might fail. We'll want to test this and see, but in terms of best practices something safer would be to define

def _ensure_mode(context: bpy.types.Context, mode: str) -> None:
    """Switches to the desired mode if not already there."""
    if context.object.mode != mode:
        bpy.ops.object.mode_set(mode=mode)

# Usage:
_ensure_mode(context, 'PAINT_GPENCIL')

Something like that =TEST THIS=
