Window Extensions, MarkColorAsTransparent does not make the color hit-test transparent

[DiegoG1019]

Problem

When marking a specific color as transparent with SDL2.NET.Extensions.Windows.WindowExtensions.MarkColorAsTransparent(this Window, RGBColor), and rendering the color on-screen, the colored pixels are transparent to what's behind it -- However, hit-tests still act upon the Window

Expected Behaviour

For the window to be transparent both graphics-wise and to hit-tests

Reproduction

// ...
var app = SDLApplication.Instance();
RGBColor background = new RGBColor(1, 1, 255);
app.MainWindow.MarkColorAsTransparent(background);
// ...
while (true)
{
	app.UpdateEvents();
	app.Clear(background);
}

Using this code, you should notice that while the screen does become completely transparent, the Window still takes ownership of Hit Tests on it

Notes

Possibly a problem with color encoding in SDL2.NET.RGBColor.ToUInt32. The old way is commented out right above it, and... it kinda works in the opposite way: The color is NOT set as transparent, instead drawn normally on-screen; but the Window is transparent to hit tests
