Increase glass pane placement hitbox

I find it difficult to place glass panes (and by extension, iron bars) on top of each other. This is due to the small placement hitbox of glass panes, which is small even among small blocks. Hanging banners have a 2px wide hitbox, while torches and fences are 4px wide, and flowers are 6px wide.

Increasing the size of the glass pane hitbox by adding 1 pixel on the X and Z axes (2x16x16 to 4x16x16) would make it easier to place glass panes on the edge of each other and be consistent with the torch hitbox.
This should not affect entity movement, only block placement.
