d4e068ae12 Handle halfword and byte DMA register writes 2015-11-06 17:56:41 +01:00
Lionel Flandrin
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.

cc07796ffe Implement many GPU quad and triangle rendering commands. 
Implemented GP0 commands 0x2a, 0x2e, 0x34, 0x36, 0x3c, 0x3e and 0x7c.

We can now reach the first level of Crash Bandicoot (Japan), albeit
with major graphical glitches.

d203a70927 Implement partial semi-transparency support in OpenGL renderer. 
For now all semi-transparent primitives are rendered with 50% opacity
regardless of the current semy-transparency mode.

2793e4211e Migrate to glium. 
I tried to follow the existing code as close as possible. It should be
equivalent.

- Remove buffer.rs, error.rs and shader.rs to use glium builtins
- Remove automatic color normalization (see
  https://github.com/tomaka/glium/issues/1313)
- Add a Vertex struct
- Modifie Color and Position
