A Windows-specific class that temporarily sets the DPI awareness context of
|
|
the current thread to be DPI unaware and resets it to the previous context
|
|
when it goes out of scope.
|
|
|
|
If you create one of these before creating a top-level window, the window
|
|
will be DPI unaware and bitmap strectched by the OS on a display with >100%
|
|
scaling.
|
|
|
|
You shouldn't use this unless you really know what you are doing and
|
|
are dealing with native HWNDs.
