Fix two bugs when deciding to tile. Large images were always tiling.

usedTileBytes was actually usedTileTexels, so we underestimated how much
of the image we were using by a factor of 4.

Then, to determine if we were using more than 50% of the image, we wrote:
usedTileBytes < 2 * bmpSize;

That meant we were off by another factor of 4.

GrTessellator (AA): Fix for missing fill artifacts.

Some regions were being incorrectly filled due to setting
connector edges winding to zero *after* merging collinear edges.
This would cause the merge to add the wrong winding value. Putting the
adjust before the call to merge_collinear_edges() fixes the problem.

Also, some pixels were not getting coverage due the inner edge being
+1 winding. Using -2 winding for inner edges ensure the interior
regions are -1 winding, which gives coverage in more cases of
self-intersection. This required flipping the comparisons on the
intruding-vertices workaround.

GrTessellator (AA): improve AA quality for near-overlapping paths.

When path features are very close together, the outer contours can
overlap. This causes the connector edges (the ones joining the inner and
outer vertices) to intersect other edges. Lerping the alpha along the
connector edge gives us a good approximation of the coverage at that
point.

GIF: Only report a frame after knowing dependency

Previously, getFrameInfo might report a frame that was truncated prior
to setting its requiredFrame. As a result, fRequiredFrame may be
different depending on how much data has already been received.

If there is a local color table, do not report the frame until the
color table has been received, since that is used to determine
fRequiredFrame. If there is no local color table, set fRequiredFrame
and report the frame after reading the header.

Add a test.

Replace make_from_resource with GetResourceAsData
