316338a4eb Correction of the non-portable use of dynamically allocated stack arrays in the 
pdf shader code.

I briefly looked into making use of alloca, but that is also non-portable, and
deprecated in many environments.  Fell back to the SkTDArray class as a common
denominator.

This problem was introduce by the following CL:

da912d61ed [PDF] Add support for Shaders. 
- Shaders, or as they are referred to in PDF, patterns, are drawn in the coordinate system of the initial page, so when we canonicalize them, we have to consider the current transform and where they are constructed.

- Image shaders are tiled by default, this makes repeat and mirror modes easy, but means we have to draw a pattern as large as the current clip to support clamp mode.

- Gradient shaders are implemented with type 4 functions, which are basically small snippets of post script code.  I've tried to make the code generation modular and heavily commented to make it easy to understand or expand.

759876a922 Our region blitter (invoked by region::setPath()) must have its scanlines 
fed to it in scanline order (Y sorted, then X sorted).

If, however, we call rgn->setPath(path, otherRgn) with path in inverse mode,
then our scan converter code looks like this:

if (inverse)
    blit_top
scan_convert_path
if (inverse)
    blit_bottom

This is fine, unless otherRgn is complex. If it is, then blit_top will want to
efficiently "blit" otherRgn (the part above the path), and that means calling
blitRect in an iterator. That can result in chunks being passed to our blitter
(which is really accumulating scanlines) out of scanline order.

The change is to detect that otherRgn is complex, and if it is, just perform
the op in two steps:

1. setPath on a tmp region, limited by the bounds of otherRgn (simple)
2. intersect this tmp region with the currRgn.

This is effectively what we do for non-intersect ops. Intersect was different
only because we could (sometimes) avoid the step of create a tmp region.

d302f1401b Add support for clipstack to Gr. GrClip is now a list of rects and paths with set operations to combine them. The stencil buffer is used to perform the set operations to put the clip into the stencil buffer. Building Gr's clip from Skia's clipStack is currently disabled due to the fact that Skia's clipStack is relative to the root layer not the current layer. This will be fixed in a subsequent CL.
