Had to manually inform the shader of the local-to-world matrix.

Note: due to bug in interpreter, point-light sample can't run in raster

3 new getters:
- localToWorld
- localToCamera
- localToDevice (same as total-matrix)
The current tracking minimizes overhead, by using a computed inverse to
produce the localToWorld/Camera. This can be change as needed in the
future (more precision, but more memory/overhead), but for now is
sufficient to try out the new APIs.

Propose a standard way to talk about the camera (etc) in SkCanvas:
- client provides 3 matrices: viewport, projection, camera
- canvas->concat(viewport * projection * camera * invert(viewport)
- camera and projection are taken straight from the textbook for 3D
- "viewport" means a matrix that transforms +-1 square about the origin
to the clients working canvas. A simple way to describe it is:
"specify the area-of-interest with a rectangle and z_scale"
Expose the ctm as a 44 from canvas for now. Likely we will add these
3 new matrices to canvas, and each may have a getter.

The reason for the assert was breaking an assert, that if the CTM was scale/translate, that after
a preTranslate, it should still be that.
This is true... unless the new translate values are non-finite. In that case, we might turn a zero
into a NaN, (0 * non_finite --> nan), so we either have to require finite args (which we don't
at the moment) or we can't make this assert. This re-land removes that assert.
This reverts commit 268ed57d71.

Before we write too many of these, let's get a program() / onProgram()
wrapper in place for SkColorFilter. When a filter claims it doesn't
change alpha, we can skip any work it might do to "calculate" that
unchanged alpha (e.g. 0*r + 0*g + 0*b + 1*a + 0) and instead just
save and restore the orignal alpha.
SkShader already has this same program() / onProgram() setup, and uses
it similarly to force any shader that claims to be opaque to be opaque,
replacing any math (or sometimes even memory loads) that shader may have
done to produce alpha with a simple splat(1.0f).

This catches cases where the matrix bottom-row might look like
[ 0, 0, not_one ]
That would get categorized as perspective, but in reality that matrix
behaves like affine. If we can detect that pattern, and scale the entire
matrix by 1/not_one, we don't change its behavior, but it will now be
categorized as affine (seen as simpler/faster).
