Block hitboxes still cause semi-transparent blocks not to render behind them in lower than "Fabulous" gfx settings

The bug

When looking at a block, the hitbox still causes semi-transparent blocks behind it (such as water, honey blocks, or stained glass) to not render, in graphics settings other than Fabulous.

This could potentially be fixed by simply making the hitbox opaque for those graphics settings, rather than translucent.
