I have a question about the way Plasma::Svg::paint is supposed to work
when an elementId is given, but a size is not.
The context for this is a bug I was fixing in bubblemon. The bubblemon
SVG has three elements; the background, the glass and the bubble. The
bubble is smaller than the other two elements.
The bubblemon applet resizes the bubblemon SVG to fit, and can retreive
the scaled size of the bubble using Plasma::Svg::elementSize. This
works as expected: if the SVG has been scaled to half its natural size,
m_svg->elementSize("bubble") will return a size half the natural size of
the bubble element.
The problem comes when doing m_svg->paint(p, QPointF(x, y), "bubble").
This will not paint the bubble at the scaled size. Nor will it paint
the bubble at the bubble's natural size. Instead, it will paint the
bubble at the size m_svg->size(); the scaled size of the whole SVG.
My question is: what is intended to happen here? bubblemon was assuming
that the bubble element would be scaled appropriately. However, the
systemtray applet, for example, assumes the current behaviour when
drawing the "show hidden tasks" arrow. The API documentation doesn't
say either way.
