What feature would you like to be added?

Now mipmap images in an Image are always deallocated whenever DrawImage is called. This is problematic when the Image is an offscreen and is often rerendered. Actually, this caused unnecessarily GPU memory allocations and deallocations. We should keep the mipmap objects and reuse them.

Why is this needed?

For performance.
