Slicing - set Minimum Size to 1 x 1, the Sprite Editor window and Unity editor freezes. It creates 150.000 textures and user has to force quit the editor. Maybe there should be a warning that user can insert a minimum value?

Prerequisite:

You need a sprite in you assets

Repro:
1. Select the Sprite from the asset
2. In the Inspector, select Sprite mode > multiple
3. Select Sprite Editor,
4. In the sprite editor click on slice
5. in the slice dialog - set it to Grid and set size to 1 and click on slice

Result: the Sprite Editor window and Unity editor freezes. It creates 150.000 textures and user has to force quit the editor.

Expected result. The user should be prevented from making settings that makes the editor freeze
