I simply removed your nextpowerof2 code(so the width and height wasn't being enlarged) and saw no memory change). Obviously because they are temporary buffers, I guess?
right, the new code free() them right at scope exit.
If this is the case, then maybe there is one odd temporary still hanging around in png?
Could be, though the png itself has relatively small overhead, and the opengl texture adds to it still. I'm not sure if video memory is counted by task manager or not... but it could be loading up the whole ogl driver that accounts for some of it. I don't know.
