WineFix patch: Color picker zoom view is black on Wayland

[noahc3]

The color picker tool is supposed to display a zoomed in close-up of the area around your mouse cursor to make it easier to select specific pixels, but under Wine this renders fully black.

Some quick investigating shows this tool is implemented by trying to capture the display and cropping it, but I suspect that either Wine does not implement any display capture functionality, or it does support it but configuration must be done in the parent DE to enable the necessary capture permissions under Wayland (or perhaps there is only support for X11).

Confirmed works fine in X11, this is related to Wayland display capture.

IMO patching in display capture support under Wayland is not an ideal fix, especially in DE's like Gnome where capturing the desktop requires stupid popups.

Instead will probably only allow color picking inside the Affinity windows (the color picker isn't allowed to draw or capture mouse events outside the window anyways on Wayland). This way we can just use a bitmap of the canvas component or maybe capture the full window.

The fix should detect and only apply patches if running under Wayland, since the native implementation works & has more functionality than we can get under Wayland without stupid workarounds.
