When using WED, look at the "title bar" for each display window.
Look for "Grid: 16 * 8" or "Grid: 128 * 8".
The numbers displayed depends on the zoom factor for the window.


The first number indicates the number of quants each grid-square occupies.
The second number usually stays "8" - meaning you have 8 small grid-squares
in 1 *large* grid-square.

This helps in determining the actual size of a rendered surface
- depending on which window you're looking at (Top, Bottom, or Side).

So, if you have a block drawn at "Grid: 16 * 8" that measures 4 * 2 small grid-squares (4-wide, 2-high),
you'll need a texture thats 64 * 32 - 16*4 wide by 16*2 high.

This is just something I've noticed, not necessarily from the manual...
