shape of tech tree nodes

[theJesuit]

Hi anyone,

I just had a thought, but not being near my computer for another 23 hours, could anyone please tell me what the answer might be?

Could tech tree icons be changed to be rectangles? Possibly by changing the shape of the png file?

Currently the tech tree icons can be 64x64 pixel png files.  What happens when you simply make it 64 x 32?  Is it stretched, failed to load and replaced by a generic icon? 

Thanks for any heads up!

Had a very quick trial today.  No go. It is a stretch of smaller icons to the square shape.
