Update header divider

[Tim Peeters]

Use color: 5% black instead of the current image.

[Tim Peeters (tpeeters)]

Currently we use two images for the divider. From PageHeadStyle.qml:
    separatorSource: "artwork/PageHeaderBaseDividerLight.sci"
    separatorBottomSource: "artwork/PageHeaderBaseDividerBottom.png"

11:29:15 < jounih> timp - can you please check how Dash has implemented the suru divider? they just used qml rectangles
11:29:30 < jounih> timp: they also have the right color values. so you could just copy it from there

[Jouni Helminen (jounihelminen)]

let's use QML rectangles for the top (inner shadow), middle (large divider) and bottom (highlight). The correct implementation is already in the dash divider - can we just copy the solution from there?

[Tim Peeters (tpeeters)]

not a showstopper, reduced priority

[Tim Peeters (tpeeters)]

dash automatically computes the color of the bottom and top of the divider, but the main divider color is hardcoded as #e0e0e0

I set this back to in progress, because:

159 + // lands, set separatorSource and separatorBottomSource to "" in order to use the new divider.
