Drag to select text does not work correctly when `pdf-view-image-relief` is non-nil

[rhgg2]

Describe the bug pdf-view-image-relief messes up mouse text selection on (at least) MacOS

Steps to Reproduce the behaviour

• Evaluate (setq pdf-view-image-relief 2)
• Open a pdf and start selecting text with the mouse by clicking and dragging. Each mouse drag causes the image to zoom in. At the end of selection, a single click restores the correct zoom setting.

What is the expected behaviour? No zooming, as happens when pdf-view-image-relief is nil.
