99 - Physical base address of the framebuffer, that is the address of

289 - Use the alpha channel of the framebuffer to clip or blend
290 framebuffer pixels with video images. The blend function is:
291 output = framebuffer pixel * alpha + video pixel * (1 - alpha).
292 The actual alpha depth depends on the framebuffer pixel format.
295 - Use a global alpha value to blend the framebuffer with video
296 images. The blend function is: output = (framebuffer pixel * alpha
