No window snapping without decorations on Windows

[chrisduerr]

It seems like window snapping does not work on Windows when decorations are disabled. This was tested using the Windows shortcuts, since the decorations aren't available to drag them of course.

This was originally reported to Alacritty in alacritty/alacritty#3602.

Did anyone find a solution for this ?

Also maximizing the window fills the whole monitor and doesn't account for the taskbar.

A solution for these issues can be found in this repo it is written in c++.

1. Snapping needs WS_SIZEBOX or WS_THICKFRAME and WS_MAXIMIZEBOX and return 0 in WM_NCCALCSIZE window message.

2. Maximize issue can be fixed with adjusting the client rect when WM_NCCALCSIZE window message is fired:
