Fix a typo I introduced.

I accidentally reversed the intended logic. Switch a not-equal
comparison to an equality check.

Initial implementation of statistics gathering dispath.  REGAL_STATISTICS=1
FreeGLUT refresh.
RegalClientState functionally complete.
DispatcherGlobal added for global (GLX/WGL/EGL) API dispatch layering.
Work-in-progress: apitrace dispatch layer for Regal, not enabled yet.
Added All.sln for VC10 purposes.
Android build fixups - not linking snappy and apitrace yet.
Emulation support for DSA gl(Enable|Disable)VertexArrayEXT and VertexArrayOffset commands.
Initial implementation of Draw*Elements*BaseVertex* emulation.
IBM_texture_mirrored_repeat extension emulation for ES 2.0.
Use REGAL_CALL for GLDEBUGPROC* function typedefs.
Fix logging of string in glNamedProgramStringARB.
Fix logging of commands with ref and mask.
Initial Doxygen generated Regal manual - work in progress.
Enable GL_CLAMP on ES2.0/3.0 and core GL contexts by remapping to equivalent GL_CLAMP_TO_EDGE
Add emulation support for glInterleavedArrays().
Add emulation support for DSA VertexArray*OffsetEXT routines.
RegalUtil.h namespace macros moved to RegalNamespace.h
Update uniforms after glColor().

The updates were not propagated because Iff::UpdateUniforms()
did not think that there was a change.
Extend emulation dispatch to hinting.
GLEW refresh (w.r.t opengl.org)
Some GL API harmonization with apitrace.
Add Regal support for GL_SGIX_ycrcb
Further GL_REGAL_enable support for glEnable/glDisable of dispatch layers.
DSA emulation moved to downstream of Regal::Emu::Iff
Trace dispatch fixes for WGL
Support for REGAL_TRACE_FILE setting, and JSON property.
Tidy-up of Regal::Emu::Filt
Initialize TexenvCombineState to proper defaults.

Without correct defaults some combinations miss texture data.
For example the following sequence of calls will fail to produce
RGB colors upon rendering:

  glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE)
  glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_ALPHA, GL_REPLACE)
  glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_ALPHA, GL_PRIMARY_COLOR)

The spec tells that correct defaults are:
  mode=GL_MODULATE
  src0=GL_TEXTURE
  src1=GL_PREVIOUS
  src2=GL_CONSTANT

See pages 185 and 279 at http://www.opengl.org/documentation/specs/version2.0/glspec20.pdf

Also updates paths in README.
ARB_draw_buffers emulation for ES 2.0
glReadBuffer emulation for ES 2.0
JSON support for hint emulation layer.
Leave Doxygen-generated documentation out of git repository.
Extend RegalPlugin to provide name based lookup.
Regal.h touch-ups for harmonizing with apitrace.
API database support for maps of per-platform types.
