#1 Color legend broken in perspective mode

[Knut Franke]

In perspective mode, the color legend is malproportioned and the legend axis is displayed at an angle, crossing through the gradient. Tested with QwtPlot3D 0.2.7 and Qt 4.3.3.

Probably the easiest way to reproduce this is to patch the simpleplot demo:
