 H.264 (AVCHD) and MPEG are CODECs for encoding video. Typically they
have to be decoded for display.

 If by "graphics" you just mean images, you likely need to learn the
basics of the X-Window system (or whatever is being developed to replace
that on modern hardware); or look for an image viewer program (irfanview,
gimp if you want to edit too). If you mean /plots/ or /charts/ (to use
Excel nomenclature), the matplotlib add-on for Python, R statistics program
(though Mathematic is already installed on the NOOBS/Raspbian image)

 To my knowledge, Broadcom has not released very much information about
the GPU. Consider that the initial booting of an RPi is done by loading a
certain file into the GPU, and that file than loads/starts the ARM
processor.
