* to work around this:
*
* Option 1: Alter the position of the rect that we send so that we cancel
* out the positioning effects of SetLayout
* Option 2: Create a memory DC with the widgetRect's dimensions, draw onto
* that, and then transfer the results back to our DC
*
* This function tries to implement option 1, under the assumption that the
* correct way to reverse the effects of SetLayout is to translate the rect
* such that the offset from the DC bitmap's left edge to the old rect's
* left edge is equal to the offset from the DC bitmap's right edge to the
* new rect's right edge. In other words,
* (oldRect.left + vpOrg.x) == ((dcBMP.width - vpOrg.x) - newRect.right)
*
* I am not 100% sure that this is the correct approach, but I have yet to
* find a problem with it.
