52b64619d9 increase subdivision for very large cubics 
Allow 512 subdivisions for hairline cubics instead of 64
to allow very large cubics to be properly approximated with
lines.

Fix issue with state tracking in GrGLGpu::createTestingOnlyBackendTexture

Add tests for clearing GPU SkSurfaces and add tests for GrDrawContext::clear().

Add comment that SkCanvas::flush will resolve the RT in the GPU case.

afc7cce5d6 Fix for rounded-rect clips with filters. 
Don't use the base canvas size to limit raster of complex clips, since
the top canvas size may actually be larger (e.g., a blur filter which
expands the clip bounds to accommodate filter margins). Use the top
canvas bounds instead.

eae84c2e0e Image filters: fix srcOffset handling in asFragmentProcessor() path. 
Filters such as SkMatrixConvolutionImageFilter which use the
asFragmentProcessor() path were not correctly handling srcOffset.
It is correctly applied to the bounds, but the srcRect and dstRect
were computed from the pre-offset bounds.

The fix is to move them to just above where they're used in drawing.

Note: this change adds a new test case to the imagefiltersgraph GM,
so it will have to be rebaselined post-landing.

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.)

06d54ad09a Fix SkXfermodeImageFilter GPU fast path for differing sizes. 
The GPU fast path was not doing the correct thing for input bitmaps of
differing sizes. This change brings the fast path in line with the
slow path: use the union of foreground and background bounds as bounds,
offset the draw context by the bounds translation, and translate the
foreground and background independently by their respective offsets.

Finally, we add a texture domain for the background fragment
processor, since we may access texels outside its domain.

Note: this adds two new test cases to the xfermodeimagefilter GM, so
those will need to be rebaselined.

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).

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.
