I'm trying to port the Just Another Improved Greenhouse Mod to 2.1, and unfortunately it's not liking the prototype graphics for some reason.
The actual greenhouse is a 320x320 png, but the game doesn't seem to accept it at that size.

This worked fine for 2.0

Was something changed to enforce powers of 2, since it seems to want a 512x512 image????

Is there anything I can do about this?

Okay this works if I use a 512x512 image, but I'm not sure why powers of 2 would now be required. Is this a bug, or a SDL3 change, or something?

OKAY I FIGURED IT OUT

For the research image, I set the icon size to 512x512, when the source image is 320x320

This worked in 2.0, it would simply add transparency and handle the larger image fine, but for 2.1 it errors and doesn't allow exceeding the max size of the image.

This is fine for my case as the Research image should have been 320x320 anyway (512x512 was a mistake), but other mod authors should know about it.
