Possibility to adjust the bounding box

In some images of QtGraph surfaces, sometimes objects at the very edge of the bounding box are missing. As a workaround it’s possible to add a tiny offset to the bounding box given by the axes range. The downside is, that this also affects the axes.

Would it be possible to have an API so that one could add an epsilon to the bounding box of the geometry for the underlying renderer.

(The missing objects issue was there already with DataVisualization)
