Vram map - suggestion

[matthewh626]

As the title suggests, I think a table similar to the memory map but for the vram would be very helpful (especially for the cgb) as the layout of the vram isnt obvious and the information about it is very spread out thought the graphics section so a full table with the address ranges and their use (maybe at the top of the main graphics page) would be very helpful.

idk if it would be necessary, but because of the second bank not being just a copy of the use of the first due to the whole bg attribute feature a second separate table could help clarity greatly
