Optimized absolute position clicking and fixed issue where cursor would return to top left of screen

[jlipton04]

Using this autoclicker, I noticed that periodically the cursor would move/appear in the very top-left of my display. I read some of the XLib docs, and found that we can avoid the first call to XWarpPointer(), which moves it to (0, 0), by defining the DestinationWindow as DefaultRootWindow() in relation to the display value. This essentially achieves the same result but without the unnecessary cursor movement.

I can't find any reason this would break existing use-cases, but please let me know if there are any tests I should run. I was able to test/verify this change on my personal machine without any apparent regressions.

Hm I wonder why I set it to the absolute position originally

If you know that this works I can merge

Yeah, it works. You can see here that this DefaultRootWindow() function is used to get the coordinates initially, so using it as the anchor for those same cursor coordinates here makes sense and should yield the same absolute position on screen.
