Script to resize existing sprite to the multiply of 4.
The script of resizing was taken here https://github.com/ababilinski/unity-gpu-texture-resize
#How it works
- Enable read/write option on texture/sprite.
- Disable compression if there is. It wont work with compressed textures.
- Right click on texture -> Resizer -> choose the proper option.
- Now you can disable read/write option and choose the compression.
