Background: I'm writing some articles on Minecraft in an attempt to introduce 10-year olds to development through modding. I know very little about the game itself, though :)
I'm trying to understand why Minecraft appears to run in an "odd" default resolution. Grabbing a screenshot, I think it's rendering at 550x310 but that doesn't seem to match any of the "common" aspect ratios (although it's close to 16:9), nor is it evenly divisible by 16, which appears to be what the texture packs use.
Is it actually running at 550x310 in its default windowed mode? If not, what is the resolution?
Depending on the answer to the first question, why isn't it using one of the standard aspect ratios? I'm not familiar with OpenGL programming either so perhaps there is a common resolution close to what I'm guessing at that would make perfect sense.
