Improve window resizing on Windows

[dossalab]

...Or at least make window border non-resizeable (for example, if root width & height properties set in css)

make window border non-resizeable

You can try to set min size and max size, like this:

root {
  min-width: 900px;
  max-width: 900px;
  min-height: 600px;
  max-height: 600px;
}

This seems like a solution, but there are problems:

1. Cursor still will became double-arrow at the border
2. Window maximize button will not be disabled
3. Clicking maximize button will move window to the random location on the screen

What do you think of the following solution?

1. If min-width == max-width, then disable window width adjustment, and the height is also.
2. If root widget has maximum size limit, then disable the window maximize button.

Completely agree

For the problem in your screenshot, LCUI dose not re-render content when resizing window, I found a solution:
