If you want the background clipped to the rounded border, and the

Is that possible to dynamic creating the border/background of the root,
by modify the underling code in mozilla source code.
That's possible at least on windows. It seems you need to clip the root
window to the
rounded border on windows. On windows, the shape of the root window is
rectangle and
cannot be changed by css style. If you want to customize the window
shape, say, making
rounded border, you should do that by calling windows API -
SetWindowRgn[1]. The
code may look like this:
// The root window handle
HWND hWnd = ...;
RECT rect;
GetWindowRect(hWnd, &rect);
INT32 width = rect.right - rect.left;
INT32 height = rect.bottom - rect.top;
SetWindowRoundRgn(hWnd, width, height, iCornerWidth, iCornetHeight);
void SetWindowRoundRgn(HWND hWnd, INT32 iWidth, INT32 iHeight, INT32
iCornerWidth, INT32 iCornetHeight)
{
HRGN hRgn = CreateRoundRectRgn(0, 0, iWidth , iHeight,
iCornerWidth, iCornetHeight);
SetWindowRgn(hWnd, hRgn, true);
DeleteObject(hRgn);
}
