Image width and height needs to be a multiple of 4.

This is true, but what is the issue here?

I don't remember. If it fixes things for you, then it is probably what's required. You can verify by following the PNG decode path, which explicitly calls something related to...

There is only one way to decode the ETC data (i.e. transform the ETC binary stream into vec4 RGBA fields in shaders). Only input data to etcpak matters.

Do you have a trace that would show where this is a problem?

What CPU do you have? Is it a multi-socket machine?

That doesn't make much sense. TSC readings should be monotonic. On my 7950, the time between `FrameMark` calls is about 1 microsecond due to the cost of `std::cout`, and that's...

Access to some of the registers through the `mrc`/`mrs` instruction may be restricted to kernel space, depending on the kernel configuration. See 5fbb811f5d for an example of how this was...
