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.

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.)

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.

a9fbd1676c Fix SkTileImageFilter when srcRect is a superset of bitmap bounds. 
If the input bitmap passed to SkTileImageFilter does not fill the
srcRect, we were tiling this incorrectly (see the first sample
from tileimage filter -- it draws from a srcRect of 12,12 50x50
to a dstRect of 0,0 50x50. There should be no tiling at all
in this case!)

In order to fix this, we need to pad the bitmap out to srcRect,
and tile with that. In order to tile correctly in the GPU case,
we need to request a tileable texture.

NOTE: this will change the results of the tileimagefilter GM (correctness,
and added src / dest rects).

bad23dc9ed SkPaintFilterCanvas skip-draw support 
At the time SkPaintFilterCanvas was introduced as a SkDrawFilter replacement,
no clients were relying on the draw veto logic.  Now Chromium does.

To facilitate migrating off SkDrawFilter, let's augment SkPaintFilterCanvas
with skip-draw semantics.

A side effect of the CL is that now we call the filter virtual even for null
paints.

77b6ba3b6e Implement an SkPaint-based image filter 
This implements SkPaintImageFilter, and is intended to replace
SkRectShaderImageFilter. By allowing a paint and not just a
shader as input, this allows consumers to control dithering.

cdee009886 Add a class representing texture swizzle. 
Store config swizzle GrGLCaps and shader swizzles in GrGLSLCaps.

Remove GrTextureAccess's swizzle and update users of it to swizzle in their shader code.

defa0daa6a Clean up SkXfermode_opts.h 
It seems that MSVC + __vectorcall don't play well together,
so back ourselves out into a situation where we don't need it.

   - Inline transfermode functions.  This removes the need for SK_VECTORCALL.
   - Remove 565 destination specializations.
     Blending into 565 is not speed-critical enough to merit the code bloat.
   - Removing 565 specializations means a bunch of Sk4px code is now dead.

8888 xfermodes generally speed up a bit from inlining, smoothly ranging from no change down to 0.65x for the fastest functions like Plus or Modulate.

565 xfermodes generally slow down because we're doing 565 -> 8888 and 8888->565 conversion serially[1] and using the stack, smoothly ranging from no change up to 2x slower for the fastest functions like Plus and Modulate.

[1] the 565->8888 conversion is actually being autovectorized
