The logo I got was 4000x1200, which GLU would scale to 4096x1024 at run-time. Yours will scale to 2048x512. My cropped one will scale to 2048x1024. If you scale my cropped one in half, it would be a more fair test, since the actual bat in my cropped one is twice as big as the bat in his updated one. However, my cropped one is still under 2048 in each dimension, so leaving it alone provides a higher quality end result.

Why are you/glu scaling images? Modern drivers don't care about power of two anymore (maybe the internals do but that's their problem).

In LDCad I'll check if the driver needs power of 2 if so I generate a padded image and use uv of <1.0 to compensate. I only apply scaling (down) if the image is above the max supported texture size.

I'm using GLU to generate the MIP-maps. Do you use MIP-maps? Because I'm pretty sure they're required to be power-of-two.
