Baixar SageThumbs 2K 2.1.2 per a Windows

## What's changed

### Fixed

- **"Build thumbnails here" only ever pre-built the smallest icon size.** It prepares three
sizes, one for each of Explorer's Medium, Large and Extra-large views. It turns out Windows
renders only the **first** size it is asked for and fills the other two in from that one, and
we asked for the smallest first. So the two larger views were being filled from a 96-pixel
picture, which Windows then threw away and rebuilt from scratch the first time you actually
opened the folder in one of them. The run reported success, and for those two views it had
genuinely done nothing.

It now builds the largest size first, so the smaller ones come from it for free. In a 25-file
test, opening the folder at Extra-large afterwards dropped from 2.8 seconds to 0.1. Pre-building
still renders each file exactly once; it takes a little longer per file now, because that one
render is finally happening at the size that was actually needed.

This also corrects something the 2.1.1 notes said: the sizes were never each re-rendering the
file. There was only ever one render per file. It was just happening at the wrong size.
