Sprite Atlas Preview does not pack some of the textures that have a resolution size small enough to fit
Reproduction steps:
1. Open the attached “Test VP8.zip“ project
2. Select 4096 as Max Texture Size in “UI Atlas” Sprite Atlas
3. Press the “Pack Preview” button and observe the generated Preview window
Expected result: All textures that could be fit into the selected Max Texture Size are rendered in the Preview window
Actual result: Some textures that could be fit into the selected Max Texture Size are not rendered in the Preview window

Resolution Note:
This packing behavior is intended, when packing exceeds more than 1 page, subsequent sprites are packed such that the last page is tried first (as this is created anyway) to the first to ensure
1. Faster packing, it does not have to check the mostly full first page each time for available space
2. Uniform distribution.
