/* DrawThemeBGRTLAware - render a theme part based on rtl state.
|
|
* Some widgets are not direction-neutral and need to be drawn reversed for
|
|
* RTL. Windows provides a way to do this with SetLayout, but this reverses
|
|
* the entire drawing area of a given device context, which means that its
|
|
* use will also affect the positioning of the widget. There are two ways
|
|
* 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)
