Changelog:
- massive cleanups and optimizations on the PPU core
- ~9% speedup over v099 official
This is pretty much it for the low-hanging fruit of speeding up higan. Any
more gains from this point will be extremely hard-fought, unfortunately.

Changelog:
- SFC: fixed a regression on auto joypad polling due to missing
parentheses
- SFC: exported new PPU::vdisp() const -> uint; function [1]
- SFC: merged PPU MMIO functions into the read/write handles (as
I previously did for the CPU)
- higan: removed individual emulator core names (bnes, bsnes, bgb, bgba,
bws) [2] Forgot:
- to remove /tomoko from the about dialog
[1] note that technically I was relying on the cached, per-frame
overscan setting when the CPU and light guns were polling the number of
active display scanlines per frame. This was technically incorrect as
you can change this value mid-frame and it'll kick in. I've never seen
any game toggle overscan every frame, we only know about this because
anomie tested this a long time ago. So, nothing should break, but ...
you know how the SNES is. You can't even look at the code without
something breaking, so I figured I'd mention it >_>
[2] I'll probably keep referring to the SNES core as bsnes anyway.
I don't mind if you guys use the b<system> names as shorthand. The
simplification is mostly to make the branding easier.

Changelog:
- sfc/ppu/sprite updated to use new .bit(s) functions; masked sizes
better; added valid flags instead of using magic numbers
- ws/ppu updates to use new .bit(s) functions
- ws/ppu: added line compare interrupt support
- added ws/eeprom; emulation of WS/WSC internal EEPROM and cartridge
EEPROM (1kbit - 16kbit supported)
- added basic read/write handlers for remaining WS/WSC PPU registers
WS EEPROM emulation is basically a direct copy of trap15's code. Still
some unknown areas in there, but hopefully it's enough to get further
into games that depend on EEPROM support. Note that you'll have to
manually add the eeprom line to the manifest for now, as icarus doesn't
know how to detect EEPROM/sizes yet.
I figured the changes to the SNES PPU sprites would slow it down a tad,
but it actually sped it up. Most of the impact from the integer classes
are gone now.

Changelog:
- restructured the project and removed a whole bunch of old/dead
directives from higan/GNUmakefile
- huge amounts of work on hiro/cocoa (compiles but ~70% of the
functionality is commented out)
- fixed a masking error in my ARM CPU disassembler [Lioncash]
- SFC: decided to change board cic=(411,413) back to board
region=(ntsc,pal) ... the former was too obtuse
If you rename Boolean (it's a problem with an include from ruby, not
from hiro) and disable all the ruby drivers, you can compile an
OS X binary, but obviously it's not going to do anything.
It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.

This will be another massive diff from the previous version.
All of higan was updated to use the new foo& bar syntax, and I also
updated switch statements to be consistent as well (but not in the
disassemblers, was starting to get an RSI just from what I already did.)
phoenix/{windows, cocoa, qt} need to be updated to use "string foo"
instead of "const string& foo", and after that, the major diffs should
be finished.
This archive is the first time I'm posting my copy-on-write,
size+capacity nall::string class, so any feedback on that is welcome as
well.

Basically just a project rename, with s/bsnes/higan and the new icon
from lowkee added in.
It won't compile on Windows because I forgot to update the resource.rc
file, and a path transform command isn't working on Windows.
It was really just meant as a starting point, so that v091 WIPs can flow
starting from .00 with the new name (it overshadows bsnes v091, so
publicly speaking this "shouldn't exist" and will probably be deleted
from Google Code when v092 is ready.)
