SkCanvas keeps its non-exotic drawBitmap calls for now but they
immediately wrap the bitmap in SkImage::MakeFromBitmap. This will
add a copy for mutable bitmaps, but this can be worked around by using
images directly (preferred), or marking the bitmap as immutable. In
practice, mutable bitmaps do not seem to be widely used so this is
deemed acceptable for now.
Several GMs are updated to mark the bitmaps as immutable in order to
avoid pixel churn in how CPU vs. GPU mipmaps are generated. As we move
towards explicit mipmap generation, this distinction will become less
critical, so I'm just avoiding it for now. See skbug.com/9337 for mipmap
proposal. The image diffs encountered in this CL directly related to
generating mipmaps for bitmaps already cached on the GPU vs. not on the
GPU yet.
It was decided to copy if mutable vs. never copying the bitmap because
it preserves the image guarantees the devices and canvas' rely on,
and imposing the need to inspect an image for mutability is undesired.

- 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.
