Aliaksandr Kalenik 5f7ac559a7 LibAccelGfx+LibWeb: Add support for stacking context opacity ...

For each stacking context with an opacity less than 1, we create a
separate framebuffer. We then blit the texture attached to this
framebuffer with the specified opacity.

To avoid the performance overhead of reading pixels from the texture
into Gfx::Bitmap, a new method that allows for direct blitting from
the texture is introduced, named blit_scaled_texture().
