I’d like for the Aseprite window to be transparent, at least where there is no colour drawn, so that I can put an application behind it, say for example VLC, and use that window as a drawing guide.
On win32 at least, something like CreateWindowEx(WS_EX_LAYERED,...);
and UpdateLayeredWindow();
which allows you to have an alpha channel on an app window, more or less.
It’s a crazy feature I know… but think about it
