are you saying the solution is to scale up the board image, save it, and
use that for the texture?  With single-pixel lines (as in the current
xqboard.png) that will not be pretty and the approach itself does not
scale since this way the window always has to be smaller than a fixed
size image.  Using a 9000x10000 pixel image might be practical for
window sizes a human produces, but I don't consider that a solution.

In the case of a full-board texture the user will not want any tile
overlap because that wouldn't look like the board.  Even if had second
filed-drawing function for full-board textures, XBoard would need to
know if to apply it or not.  If you object to adding a switch for
full-board mode, I don't see how full board textures would be supported
properly as of now.
