Sprite modifications are not allowed after a transform commands on scripts

[Gasparoken]

Reported internally: https://igarastudio.zendesk.com/agent/tickets/6130

The error: Cannot modify the sprite. It is being used by another command. Try again. will appear if a Sprite:[modify] function is performed after performing a transform command, example:

app.command.MaskAll()
app.command.Rotate{target="mask", angle=1}
app.activeSprite:newLayer()

This has been happening since version 1.3.3 and can easily affect custom community scripts.

Until this is resolved, use app.command.DeselectMask() after the transform function to release Aseprite from the "in the middle of a transform" state.

app.command.MaskAll()
app.command.Rotate{target="mask", angle=1}
app.command.DeselectMask()
app.activeSprite:newLayer()
