Jpcsp SVN r1981 - 模擬器

http://buildbot.orphis.net/jpcsp/

Jpcsp SVN r1981 is released. JPCSP is a PlayStation Portable(PSP) emulator
which is written in JAVA. JPCSP is the first PSP emulator that is written in
JAVA. Most people think java is too slow. But Shadow and his team has proven
us wrong. The newest Java versions are almost as fast as C which makes it
very interesting for emu dev's. Shadow and his team are working day and night
with pleasure on the emu, many coders have dedicated to the project. Because
it's written in java many young devs find it interesting to learn how the
emulator works.

Jpcsp SVN changelog:
r1980
Several performance improvements in the VideoEngine:
- improved vertex cache: changes should now be always detected (no longer
using a hash code)
- provided an asynchronous vertex cache when sceGuDrawArray can be detected
at compile time: the cache is then checked in a separate thread so that the
cache is already up-to-date at rendering time
- added a new option "Enable VAO" (OpenGL Vertex Array Object): this option
can improve the performance in some applications, but not always. It can also
reduce the performance in some cases. This is why this is only available as
an option. This option is only active when enabling the vertex cache and the
shaders.
- automatic merging of sequential "prim" commands to optimize OpenGL calls
- fast skip of GE commands having no effect (e.g. setting multiple times the
same flag to the same value)
- statistics are now disabled by default (probably only useful for devs).
They have to be enabled by DurationStatistics.collectStatistics.
r1981
Fixed problem introduced by r1980 (was sometimes causing incorrect video
decoding as reported by Darth1701).
