This is a relatively easy way to improve the rendering with the non-native theme while not regressing anything. In the future, once non-native-theme is shipped and default everywhere, I think we could provide something like: bool nsITheme::GetShadowRect(nsIFrame*, StyleAppearance, LayoutDeviceRect&, RectCornerRadii&) or such, where we can provide a precise rect + radii, and we would avoid painting the shadow if the function returned false. That would allow us to remove the native theme box shadow code path, and avoid WR fallback, all at once. Differential Revision: https://phabricator.services.mozilla.com/D109209

/* 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)
