Do any devs know why the tech tree "SimpleIcons" are saved as .png and not .dds?

I'm curious as to why the 88 tech tree SimpleIcons are saved as .png files and not .dds. I would think it would save a good chunk of memory for them to be saved as .dds, so why aren't they?

I'm not a dev, but having worked with both custom stock toolbar and tech tree icons myself, I believe I can answer this question.

Below certain dimensions (32x32 or 64x64 px), image compression actually results in significant loss of visual quality, so SQUAD and modders tend to use this as their lower limit when deciding whether to convert PNGs to DDS.
