I would like the ability to apply a background mask to aeccurvetext (curve labels), similar to the background mask for mtext. It would also be useful to be able to turn the mask on and off though a checkbox in the Label Properties dialog similar to the Dynamic, Swap and Align properties in addition to the ability to create a style with the mask property turned on.

How Used:
I would use this to mask easement lines, contours, etc. behind curve labels.
