eaa7797990 Add luminance mask transfer modes. 
This adds kSrcInLum_Mode and kDstInLum_Mode, to support CSS and SVG luminance masks (http://www.w3.org/TR/css-masking/#MaskValues , http://www.w3.org/TR/SVG/masking.html#Masking ).

The transfer coefficient is computed according to http://www.w3.org/TR/2011/REC-SVG11-20110816/filters.html#feColorMatrixElement "luminance-to-alpha":

  luma = 0.2125 * r + 0.7154 * g + 0.0721 * b

194d775edc This patch implements a crop rect for SkImageFilter. It has been implemented for SkColorFilterImageFilter and SkBlurImageFilter as examples. 
In order to preserve the immutability of SkImageFilters, the crop rect is passed as a constructor parameter. If NULL (the default), the bounds of the input image are used, as before.

This also tightens up the boundary handling for SkImageBlurFilter on the GPU backend. Where we were previously using clamping semantics, we now respect decal semantics (so we don't oversaturate the edges). This brings the GPU and raster backends into closer alignment, but will require some new baselines for the GPU tests.

At a minimum, the following tests will need new baselines: imageblur, imagefiltersbase, imagefilterscropped, spritebitmap.

d64d8a905a Working plumb of image scaling: 
1) always generate mipmaps if we detect that we are downsampling.
2) pre-scale the image if we detect that we are upsampling
   (currently valid for scale+translate only)
3) A few miscellaneous bug fixes related to image scaling.

Still need SSE/Neon versions of these image scalers.

86fc266eda Implement SkXfermode image filter. This required changing the signature of SkXfermode::asNewEffectOrCoeffs(), to add an optional background texture. 
For the raster path, we do a straightforward 2-pass method: draw background, then composite the foreground over it.

For the GPU path, if the xfermode can be expressed as an effect, we build an effect with the background texture incorporated, then do a single-pass draw fetching both foreground and background textures, and compositing to the result. If the xfermode is expressed as src/dst coefficients, we do a 2-pass draw as in the raster path and use fixed-function blending.

7def5e1630 Separate core and images project. 
SkImage calls functions on SkImageDecoder and SkImageEncoder. This
is desired behavior, and it is also desired to include SkImage as
a part of core. In order to keep core from depending on images,
update SkImageDecoder_empty.cpp to implement all of SkImageDecoder
and SkImageEncoder. This file will be built by chrome (in
https://codereview.chromium.org/15960015).

Move force_linking from SkImageDecoder.cpp to its own file. It must
be called to force linking with the image decoders if desired. Call
the function in tools that need it:
sk_image
render_pictures
render_pdfs
sk_hello
filter
bench_pictures
debugger

SkImageDecoder:
Derive from SkNoncopyable, instead of duplicating its
hiding of constructors.

skhello:
Return rather than trying to write a null SkData to the stream.

Revert "Hamfistedly removed core dependence on images"
(commit 0f05f682a90bc125323677abf3476e1027d174f5) and
"Move SkImage::encode to SkImage_Codec.cpp."
(commit 83e47a954d0bf65439f3d9c0c93213063dd70da3.)
These two commits were temporary fixes that this change
cleans up.

SkSnapshot.cpp:
Check for a NULL encoder returned by SkImageEncoder::Create.

45a75fb4d0 path ops : make it real 
Add an option to SkCanvas to turn on path
ops when combining clips. 

Allow Op() to use one of the input paths
as an output path.

Fix a bug in Op() when the minuend is empty
and the subtrahend is not (for difference).

Change the build to allow core to depend on pathops.

3f2d45aff6 (Relanding r7275 with assert fix, plus fixes from r7276, r7280, r7283.) 
Implement a bicubic resampling image filter, with raster and GPU backends.
In order to get this to work on the GPU side, I had to modify the width and height of the drawn texture in drawSprite() and drawDevice() to use the filtered texture's dimensions, instead of the source texture.  (This wasn't a problem before since all other image filters produce results the same dimensions as their input texture.)
For now, this implementation only does axis-aligned scaling (same as the Lanczos-3 implementation in Chrome).  It's also done for correctness and clarity, not speed, so there are lots of opportunities for speedups.

In cmykjpeg, do not attempt to decode in the constructor, since it
currently crashes on Mac (if you provide the correct resource path).
Even when we fix this crash there is no need to do it in the
constructor, since we create all of the gms in order to
get their names (to determine whether to run them).

5faa2dc266 Implements a matrix convolution filter (raster path only). The filtering loop 
is templated on the tiling mode for speed:  interior pixels are unconditionally
fetched; border pixels apply the appropriate tiling mode before fetching.  It
handles target, bias, divisor (as gain), and edge modes (named to be more
skia-like).  It does not handle the "preserveAlpha" semantics of
feConvolveMatrix, nor "kernelUnitLength".

f1ab723033 Change drawBitmapRect to take a float-src-rect instead of integer-src-rect. This 
allows the client more control over the scaling. Because of virtual overrides
and wanting to keep the old call-sites up and running, this CL renames the
virtual entry-point to drawBitmapRectToRect, and downgrades drawBitmapRect to
a non-virtual helper function.

The implementation is to use the float-rect for computing the matrix, but still
cons-up an integer rect for the purposes of subsetting the original bitmap. We
do this by calling float_src->roundOut(&int_src) so that we include all
(partially) covered src pixels.

No change needed on SkDevice, since that signature is explicitly passed the
computed matrix.

b2ee33c535 Implements the non-Porter-Duff compositing modes required for SVG's feBlend
