For conversions between `PixelSize` and `Size` use a scaling factor by default; rename the DPI overloads to have a `WithDpi` suffix.
In addition to `PixelSize`.
The affected members are: - `IWindowBaseImpl.Position` - `IWindowBaseImpl.PositionChanged` - `ITopLevelImpl.PointToClient` - `ITopLevelImpl.PointToScreen` - `IMouseDevice.Position` - `Screen.Bounds` - `Screen.WorkingArea`
`SetWindowStartupLocation` needs to be called _after_ the window is shown as is done in `Show`. In addition, the owner window needs to be passed so we can get the correct screen. Renamed the `parent` parameter to `ShowDialog` to `owner` as its `WindowStartupLocation.CenterOwner` not `CenterParent`.
We probably want to change this and pass the owner to the `Show` method as we do for dialogs: having owner specified in different places for dialogs vs non-dialogs is not a good API.

Based on a comment on #1979 from @kekekeks this PR refactors window positioning a little, and hopefully fixes the bugs we've been seeing around that. It does the following:
PixelSize
accept a scaling factor for conversions: conversions that accept DPI are still present for the moment but with aWithDpi
suffixPixelPoint
andPixelRect
to represent device pixel points and rectsIWindowBaseImpl.Position
IWindowBaseImpl.PositionChanged
ITopLevelImpl.PointToClient
ITopLevelImpl.PointToScreen
IMouseDevice.Position
Screen.Bounds
Screen.WorkingArea
ShowDialog
respect WindowStartupLocation: supersedes WIP: Make ShowDialog respect WindowStartupLocation. #2246Show
andShowDialog
respectWindowStartupLocation
DPI-awareness: supersedes WindowStartupLocation DPI-awareness #1979DialogsPage
to allow testing of startup location.Note: this is a breaking change
Still TODO:
Window.Owner
and pass the owner to theShow
method as we do for dialogs: having owner specified in different places for dialogs vs non-dialogs is not a good APIFixes #1961
Fixes #2207
