#i105937# Fixed a few remaining gradient glitches

* linear/axial gradient were f*cked up when border and rotation
was given
* found another place where drawinglayer was generating helper
polygons for gradients (vclgradienthelper.cxx), adapted to new
value ranges
* fixed build breakage in debug build in oox
* fixed order of gradient color generation
