Grid blocks overflowing the window region when resizing

[reisaraujo-miguel]

Describe the bug
When you launch the game and use up or down to resize the grid, you can set the grid to a size where the blocks on the edges can overflow to outside the window region.

To Reproduce
Steps to reproduce the behavior:

1. Launch the game...
2. Press down one time

Expected behavior
Resizing the grid should not create blocks that overflow the window size. A solution could be always dividing the screen by some factor, for example, dividing the window in 2x2, 3x3, 4x4 etc. (for square windows, for other aspect ratios this should be adapted).
