Multiple Master and TrueType fonts support variation axes.
This implements back-end support for axes on platforms which
support it.

High quality anisotropic is an interesting edge case for the gpu backend. For scales that are both minimizing and maximizing Ganesh falls back to MipMaps which can turn out too blurry.

This CL also adds a new parameter to SkBitmapSource which gives the user control of the filter quality.

Reason for revert:
static void draw(SkCanvas* canvas,
const SkPaint& p,
const SkBitmap& src,
SkColorType colorType,
const char text[]) {
SkASSERT(src.colorType() == colorType);
canvas->drawBitmap(src, 0.0f, 0.0f);
canvas->drawText(text, strlen(text), 0.0f, 12.0f, p);
}
This assert is firing, at least on macs, where all images get decoded into 32bit at the moment.

This path renderer converts paths to linear contours, resolves intersections via Bentley-Ottman, implements a trapezoidal decomposition a la Fournier and Montuno to produce triangles, and renders those with a single draw call. It does not currently do antialiasing, so it must be used in conjunction with multisampling.
A fair amount of the code is to handle floating point edge cases in intersections. Rather than perform exact computations (which would require arbitrary precision arithmetic), we reconnect the mesh to reflect the intersection points. For example, intersections can occur above the current vertex, and force edges to be merged into the current vertex, requiring a restart of the intersections. Splitting edges for intersections can also force them to merge with formerly-distinct edges in the same polygon, or to violate the ordering of the active edge list, or the active edge state of split edges.

Also: Add SkDeflateWStream and associated unit tests.
SkPDFBitmap is a replacement for SkPDFImage. As of now, it only
supports 8888 bitmaps (the most common case).
SkPDFBitmap takes very little extra memory (aside from refing the
bitmap's pixels), and its emitObject() does not cache any data.
The SkPDFBitmap::Create function will check the canon for duplicates.
This can reduce the size of the output PDF.
Motivation: this gives another ~40% decrease in PDF memory overhead
TODO: Support other ColorTypes and scrap SkPDFImage.

Fold alpha to the inner savelayer in savelayer-savelayer-restore
patterns such as this:
SaveLayer (non-opaque)
Save
ClipRect
SaveLayer
Restore
Restore
Restore
Current blink generates these for example for SVG content such as this:
<path style="opacity:0.5 filter:url(#blur_filter)"/>
The outer save layer is due to the opacity and the inner one is due to
blur filter being implemented with picture image filter.
Reduces layers in desk_carsvg.skp testcase from 115 to 78.

This CL introduces rendering conflicts with hairlines (i.e., the hairlines get overwritten). These conflicts are particularly visible on the following GMs (for the Ubuntu and Android gpu configs):
coloremoji & complexclip2_rrect_bw
