Okay, here we go.

1. setGridLines is operating correctly -- its default setting draws grid lines every 10 grid cells.  Your grid is only 14x10, so it's showing you exactly what would be expected.  If your goal is to have a grid line every single cell, you could say setGridModulus(1).  Also note that you're drawing a 14x10 grid but are squishing it into a square (400, 400) in the Display2D. You might instead try drawing it in proportion as a rectangle, that maybe (560, 400). 

2. The red border is a bug which was fixed in the current repository version of MASON.  Try that one.

Hope that's helpful.
