test case

with subpixel layout on, we calculate the innerTextRenderer's top logical position wrong and we push the parent element to upwards of one pixel (in default (top-to-bottom) mode)

Placing the innerTextRenderer in RenderTextControlSingleLine::layout() needs to be subpixel compliant. 
innerTextRenderer->setLogicalTop(innerTextRenderer->logicalTop() - (logicalHeightDiff / 2 + layoutMod(logicalHeightDiff, 2)));

Maybe we could call this centerInnerRenderer() to make it clear that it centers it within itself.
Also we can omit the argument name here.
