The thumbnail produced is set to have a maximum width of 128 and a 
maximum height of 96, and be resized in proportion vertically and 
horizontally.

When you drag the handles to make it bigger, the resolution of the 
thumbnail doesn't get bigger.  The editor just stretches the small image 
to the new size.  If you make it really big, that'll make the image look 
blocky.

If you want a clear version, you should insert the full sized image: 
Cclick on the thumbnail in the browser, click "Using Thumbnail" until is 
says "Using Original", and then drag that into the post.

There is currently no way to set the maximum thumbnail size to affect 
the thumbnails that are produced.

Note- To determine resize with aspect ratio inside a maximum area, I 
think this works:

xnew = ((xmax/xorig)/(ymax/yorig) >= 1) ? xmax : xorig * ymax / yorig;
ynew = ((xmax/xorig)/(ymax/yorig) <= 1) ? ymax : yorig * xmax / xorig;
