[skin] Fill anomalies in MoviePlayer Infobar

[prl]

There are anomalies in the backgrounds in the media player infobar in the easy-skin-aus-hd and Full-Metal-Wizard skins (MoviePlayer screen skin).

A fill colour is used as part of the background and it doesn't match the pixmaps used in the rest of the background.

The problem is clearer in Full-Metal-Wizard where there's a break in the fill pattern:

It's harder to see in easy-skin-aus-hd:

The OverlayHD skin is not affected, because it uses a solid colour fill background.

The problem in easy-skin-aus-hd is caused by a slight mismatch in the transparency of the central solid fill area of the infobar to the transparency of the pixmap used for shading in the bottom part of the infobar.

The problem in Full-Metal-Wizard is because solid fill shouldn't be used in that position at all (and it doesn't need to be used).

I have fixes in the pipeline.

Fixed by commits to the respective skins. In merged pull requests # 80 in easy-skin-aus-hd and # 20 in skin-full-metal-wizard.
