[1-0-1-93][Minor] Small misalignment of Pipe tiles

[NBlastMax]

Self-explanatory.

It's not necessarily self-explanatory. I had first assumed this was the result of the longstanding issues I've had with keeping grid and tile preview offsets refreshed for each copy/move/click on the canvas.

So I went through the entire system tonight, gutted some old scripts, wrote some new ones, and created fully automatic generation of preview offsets for tiles, as well as fully automating aspect-ratio correction! All of this saves me entire hours while importing new assets into the editor's code, it's going to save me so much sanity.

But did any of that kicking and screaming fix this tile misalignment? Nope! Turns out I had drawn the slope piece itself two pixels too tall! Three entire QoL bumps for the backend of the engine, and nope- it was an artistic mistake, not a logical one.

So, I'm still working on this one!
