[Windows, Terrain] Error messages generated for every crunched terrain texture on scene load or entering/leaving play mode
To reproduce:
1. Open the attached project
2. Make sure the Terrain's texture is using Crunch Compression
3. Play the scene
Expected result: Loading a Terrain with crunched texture works with no issues
Actual result: Few errors are shown:
- GetPixels32 failed: insufficent pixel buffer size (1), must be at least 4 x 4
- Failed to get pixels of splat texture
Reproduced with: 2017.2.3f1, 2017.4.4f1, 2018.1.2f1, 2018.2.0b6, 2018.3.0a1

Resolution Note (2018.3.X):
There's no easy fix for this; as stated in the Manual, "GetPixels32 is not available on Textures using Crunch texture compression.", and the old Terrain CPU base map blending requires GetPixels32. The base map blending is done on GPU in 2018.3+, so it works with crunch compression (as well as being a ton faster and not requiring a CPU copy of the texture)
