OverlayPaste resource

overlayPaste allows pasted text to overlay the screen image. If true, characters pasted into read-only areas of the screen are ignored, with the cursor continuing to move to the right. If false, pasting into a read-only area causes an error, and the paste operation is aborted.

overlayPaste being true also causes the emulator to act as if marginedPaste were true.

The default value for overlayPaste is true starting with x3270 4.1alpha7. In earlier versions, it defaulted to false.
