Table fields from glTexture()?

glTexture seems to return a nice table, with a bunch of fields containing diverse and useful information, that are apparently referenced array style
Anybody know what the various fields refer to? I'd rather not do a bunch of science.

1: texture itself
2: texture width
3: texture height
4: width ratio
5: height ratio
6: image width
7: image height

I appreciate the prompt response but have to confess that doesn't clarify much to me
Not sure how texture width is different from image width, or what the ratios are ratios of (height to width and vice versa?) I can always do some experimentation though.

Textures size is a power of 2, while image size can be anything and the ratio is needed to correctly map texture on quad
