Unity freezes when previewing huge Sprite Atlas pack
How to reproduce:
1. Open the attached project
2. Select "Pregnant.spriteatlas" in the Project
3. Press "Pack Preview"
Actual result: Unity freezes with huge RAM memory usage.
Reproducible with: 2019.1.0a13, 2018.3.1f1, 2018.2.20f1, 2018.1.9f2, 2018.1.0a1.
Notes:
Freeze also happens when entering play mode.
The sprite Atlas pack is more than 4096x4096 resolution (which most likely causes the issue).

Resolution Note (2018.3.X):
Depending on the number of sprites and the texture size involved, the memory usage can be quite high if all the sprites are included into a single atlas.
The recommended way to avoid "out of memory" is to use multiple atlases.
