[B2.1b] Issue with 3D ManiaLinks

[Timmeh7]

Dunno if this is known or was reported yet, but the height of 3D manialink elements is different, depending on whether you are in a title menu or in the main screen.

I can confirm this: Y-axis seems to be different between inside a title (Canyon, Storm), and outside of them in the main Maniaplanet menu.

First tests to port the Tetris menu to the Styles3d, and this mis-positioning is kind of annoying:

Left inside Storm, right in the main Maniaplanet menu. Manialink is of course identical.

Another thing is, that these style3d-elements seems not to use the known system from the other elements (pos/posn), but their own system. A simple Quad is on another position as the style3d with the same pos/posn value.

The positioning problem between in-title and maniaplanet-main-menu seems to be fixed with the Beta3RC1 update.

But I noticed, that the style3ds are way too bright outside of the titles:

(Again left inside Storm, right in the Maniaplanet main menu)

As the default menu uses a white font, the text would be not readable on these styles when viewed outside the titles, so please fix this, too
