/**
|
|
* Renders a region of a window into the canvas. The contents of
|
|
* the window's viewport are rendered, ignoring viewport clipping
|
|
* and scrolling.
|
|
*
|
|
* @param x
|
|
* @param y
|
|
* @param w
|
|
* @param h specify the area of the window to render, in CSS
|
|
* pixels.
|
|
*
|
|
* @param backgroundColor the canvas is filled with this color
|
|
* before we render the window into it. This color may be
|
|
* transparent/translucent. It is given as a CSS color string
|
|
* (e.g., rgb() or rgba()).
|
|
*
|
|
* @param flags Used to better control the drawWindow call.
|
|
* Flags can be ORed together.
|
|
*
|
|
* Of course, the rendering obeys the current scale, transform and
|
|
* globalAlpha values.
|
|
*
|
|
* Hints:
|
|
* -- If 'rgba(0,0,0,0)' is used for the background color, the
|
|
* drawing will be transparent wherever the window is transparent.
|
|
* -- Top-level browsed documents are usually not transparent
|
|
* because the user's background-color preference is applied,
|
|
* but IFRAMEs are transparent if the page doesn't set a background.
|
|
* -- If an opaque color is used for the background color, rendering
|
|
* will be faster because we won't have to compute the window's
|
|
* transparency.
|
|
*
|
|
* This API cannot currently be used by Web content. It is chrome
|
|
* only.
