2fbc7fa460 Make SampleApp build on Win32 (still requires glew, this needs to be fixed) 
In fbo test funciton set min filter to nearest (for systems that don't support rendering to level of a texture that isn't mip map complete.)
Add a lot more sample slides to the win32 build
Fix texture red/blue color swap on windows.

909994fbae new scanconversion technique 
This technique geometrically clips all segments against the clip bounds,
ensuring that we never send a value to the edgelist that might overflow in
fixedpoint.

Current disabled in SkScan_Path.cpp by a #define. There are a few minor pixel
differences between this and the old technique, as found by the gm tool, so
at the moment this new code is off by default.

c4cae85752 add BlitRow procs for 32->32, to allow for neon and other optimizations. 
call these new procs in (nearly) all the places we had inlined loops before.
In once instance (blitter_argb32::blitAntiH) we get different results by a
  tiny bit. The new code is more accurate, and exactly inline with all of the
  other like-minded blits, so I think the change is good going forward.

3c9b2a4a0e expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shader 
(like gradients) to support predithering. If they do, then they would suppress
kConstInY16, since they no longer are const.

The blitters now check for each flag separately, so we don't have to give up
const-in-Y in the 32bit case, since in that mode we don't care about dithering.

cafc9f9e80 fixes around isOpaque and dithering 
- copyTo() now preserves isOpaqueness, and BitmapCopyTest tests it
- bitmap shader doesn't claim to have shadespan16 if dithering is on, since its
  sampler doesn't auto-dither (note that gradients do auto-dither in their
  16bit sampler)
- blitter setup just relies on the shader to report if its 16bit sampler can be
  called (allowing gradients to say yes regardless of dither, but bitmaps to say
  no if dithering is on)
