1a7eb26664 resolution dependent path measure 
When a dash is drawn through a canvas with a scaled up
matrix, path measure needs the pixel resolution through
the matrix to construct the dash with sufficient
resolution.

Pass the resolution through to path measure.

Replicate chrome bug in skia GM.

d4387ea993 fuzz: list API fuzzing options if -t api and -n matches nothing. 
Today we segfault if --name is empty.  This fixes that too.

This updates some terms: -t api lets us fuzz an API.

dba5734409 Seperating our fuzzing binary from DM produces a 50x speed increase for decoding images and a 10x speed increase in decoding/rendering Skps. 
This also lets us differentiate between the decoding of Skps and the rendering of them, the latter of which may be more interesting for bugs.

bf361d3ba2 remove fragile assert 
The assert basically wants the following to always be true (but it aint)

floor(int + 0.5 + float) == floor(0.5 + float) + int

... where int + 0.5 happens first, and then we add the float.

e179a9167f Texturing support for RECTANGLE textures. 
Uses textureSize() to unnormalize texture coords when reading from a RECTANGLE texture. Because of this we also require a later GLSL version to use rectangle textures (1.40).

Note that this causes a issue with the bicubic effect. The texture coords seem to have poor precision and the result is ugly. textureSize() is intended as a workaround until effects can be updated to handle unnormalized coords themselves.

Updates places where we were looking for OpenGL version 3.2 for rectangle support. It was actually added in 3.1.

1ea67a31c5 Fix SkAlphaThresholdFilter bounds handling. 
SkAlphaThresholdFilter was always allocating a mask texture
of the same size as the source texture. In addition to
potentially wasting VRAM, this could cause the mask to be
offset from the source texture, if the resulting bounds
were a different size than the source texture.

The fix is to allocate a mask texture only as large as the
bounds, and to offset it to the bounds origin on draw.

b6474dd1a5 fix circular dashing 
Path measure cannot use the same code approach for quadratics
and cubics. Subdividing cubics repeatedly does not result in
subdivided t values, e.g. a quarter circle cubic divided in
half twice does not have a t value equivalent to 1/4.

Instead, always compute the cubic segment from a pair of
t values.

When finding the length of the cubic through recursive measures,
it is enough to carry the point at a given t to the next
subdivision.

(Chrome suppression has landed already.)

a913275bda SkStream/Priv cleanups 
Replace all callers of SkCopyStreamToStorage with SkCopyStreamToData,
which is simpler and does the same thing.

Remove SkStreamRewindableFromSkStream, which is unused.

973d92cf91 SampleApp: Remove SkWindow::setColorType 
Remove SkWindow::setColorType, it is used wrong and inconsistently.

The color type is actually property of window backbuffer, used when the
window is painted with software. This is as opposed to a generic window
property that would affect all operation.

Similar to MSAA sample count for window GPU backbuffer, the bitmap
backbuffer color type should be a parameter of "attach" or "create
window" functions, should this property ever be added back.

The apps use the call wrong, setting the type as kRGBA_8888
or kBGRRA_8888 without no apparent rationale. These color types
are incorrect, as the raster surface can not work with these.

Reorganize the SkWindow::resize, since no change in SkWindow backbuffer size does not neccessarily mean that SkView would not need the call.

Do not show the sw backbuffer color type in SampleApp title, as
it does not really provide any information. On small screens,
kBGRA_8888_ColorType fills up the whole title.

3ca7336049 SampleApp: remove SkWindow::onPDFSaved, it does not work 
Remove SkWindow::onPDFSaved, it does not work and it is not used anymore.

Also, it is very SampleApp -specific feature implemented in SkWindow class.
SkWindow class is probably intended to be more app-agnosting than
what this method implies.

Presumably the idea of the callback was to inform the user of
SampleApp that the PDF was saved to a certain location.

For Android SampleApp, show a hardcoded toast that the PDF was saved to
/sdcard.
