Powered rails on slopes have a flipped sprite.

When placing a Powered Rail on a slope, it looks correct, when inactive. However, when it has been activated by a Redstone signal, the graphic flips, so that it looks like it is mounted on a slope facing the opposite direction. It works correctly in actual functionality, but the graphic for it is flipped.

Attached to this message are two picture. One shows the rail correct when not activated. In the other, I have placed a Redstone Block next to it so that it is activated.
