<mzanetti> I'm using 20 px/gu and it seems a DPR value of 4 fits nicely
on the apple retina display that is
On my galaxy Nexus, GRID_UNIT_PX=18 and QTWEBKIT_DPR=2.0
So unfortunately there doesn’t seem to be a direct proportional relationship between GRID_UNIT_PX and QTWEBKIT_DPR.
This very probably depends on the density of the display.
