bsnes/snesreader/libjma/winout.h
byuu 46a1eb8cce Update to bsnes v059r06 release.
This is an experimental release, as such it is posted only to Google Code.
Changelog:
    - 21fx API moved to pre-finalized form as S-MSU1; more about this on the forum
    - OpenGL driver now uses GL_CLAMP_TO_BORDER instead of GL_CLAMP_TO_EDGE to support screen curvature shader
    - rewrote file open dialog; code is greatly simplified, interface is improved
    - all cheat code columns are now enquoted, and empty codes at the bottom of the file are omitted (format is compatible with previous releases still)
    - debugger: added missing DMA variables to S-CPU properties viewer
    - snesfilter: added OpenMP (multi-threading) support to HQ2x filter
    - lots of other miscellaneous code cleanup work
