Is there in-depth info on how all these numbers work. I've set window size to 512, 512.. and then in the layout I've set layout size to 512, 512 and margins to 512, 512. I would have thought that 512, 512 size would be the size of my window. But if I put a block in that canvas, covering the the whole 512 area, there's still white space.. I have to stretch the block to the right, into the grey, in order to actually cover fall the white of the screen in the browser...
Is there a way to disable window sizing?
