Just wanted to report a bug I've noticed. The rectangle selection tool can sometimes shift location by a couple of pixels if I'm zoomed in while using it and then zoom out or more in at any point while adjusting the selection box. So, for example: Let's say I zoom in to select a precise corner I want within an image and then use ctrl+mouse wheel to zoom out so I can quickly drag the selection tool to select the other corner. I may need to zoom back in again to get that second corner to finish off the selection box, then, once I let go of the tool and zoom all the way back out I'll occasionally find that the corner I had just selected prior has now moved by a pixel or two.
