/**
* Blur the gameplay background for the pause menu.
*
* The blurred image is 30x40 pixels at 16 bits per pixel. At standard
* resolution this is 1/8th the size of the framebuffer.
*
* This function reads the framebuffer in blocks of 8x8 pixels. Each block's
* R/G/B components are averaged and used to set a pixel in the blurred buffer.
*
* If hi-res is being used, every second horizontal pixel on the framebuffer is
* read instead. The blurred image is the same size regardless of hi-res.
*
* The transition effect when pausing and unpausing is implemented elsewhere.
* It's a simple fade between the source framebuffer and the blurred image.
* Only one blurred image is made.
