b7014b6737 Support reading from CD-ROM XA mode 2 form 2 tracks 
This seems buggy (since we don't retrieve the entire sector data) but
Spyro does just that during the intro sequence. Maybe it's caused by
an other emulation bug or maybe it's really supposed to do that. Needs
more investigating. At any rate a warning is displayed when this code
is triggered.

direction...

bea980fff4 Implement indirect rendering and basic video output 
Instead of drawing directly to the screen we first render the entire
framebuffer to a texture and once per frame we display the visible
part of the framebuffer on the screen.

50f4bf4baa Implement polyline draw commands in the GPU 
Refactor GP0 handling code to use method pointers for dispatch. Makes
it easier to handle command with a variable number of arguments like
polylines and image loads.

4b4a6062ca Better handle asynchronous events in the CDROM controller 
It's far from perfect but it handles processing commands while we're
reading disc sectors without missing an interrupts.

Enough to reach Spyro's start screen (NA version).

a8d19c03dc Redesign memory access infrastructure 
Previously for Byte and HalfWord store we would only pass around a u8
and a u16 respectively. This is not accurate when accessing certain
device registers since some devices ignore the requested access width
and may use more than the expected number of bytes from the source
register.

Now we always pass the entire register value in a u32 instead, it's up
to the device implementation to select what it needs to use depending
on the Addressable width.
