CURA-12752 The previous method was not efficient enough in case of large models, where a single painting stroke can easily cover almost the whole texture (in bounding box). Reverted to the version where the whole texture is counted, but cached in the SliceableObjectDecorator and updated on timer so that it is not done during painting.
