a612d4c513 Implement a resize image filter. This is needed for the "filterRes" feature in SVG filter effects, which specifies the required size for intermediate processing buffers. In order to make this work, we need to render the primitive at the given resolution (doable at the callsite in Blink), and then to resize the result to the actual on-screen size. The latter is where this filter comes in. 
It simply applies a scaling factor (and the current CTM) to its input, and draws its input bitmap at that size.

e93e1dbf0e Implement srcRect and dstRect functionality in SkBitmapSource. This is required for the "preserveAspectRatio" options of SVG's feImage. Covered by new GM "bitmapsource". 
This also includes some changes to the xfermodeimagefilter and tileimagefilter GMs to properly handle the CTM. This worked before only because SkBitmapSource was ignoring the CTM. Now that it respects it, we need to give the correct transform. This also means the GMs now work while zoomed. It also implements CTM support for SkTileImageFilter.

NOTE: this will require rebaselining a number of imagefilter GMs on Nexus4, since they render in perspective (using the CTM). The changes to the results should all be improvements.

af35920e6d Implement srcRect and dstRect functionality in SkBitmapSource. This is required for the "preserveAspectRatio" options of SVG's feImage. Covered by new GM "bitmapsource". 
Note: I initially implemented this as a fully-generic SkResizeImageFilter, but then I realized that the dstRect should always be transformed by the filter matrix, but that the srcRect should not (since it's specified relative to the dimensions of the original bitmap). Since this would be confusing for someone attempting to use this as a generic resizing filter, I decided to build the functionality into SkBitmapSource instead.

d494b09f55 Align SkLumaColorFilter with the spec. 
The spec requires the resulting RGB channels for LuminanceToAlpha to be
0 (and not just scaled by the luminance value</facepalm>):

  | R' |     |      0        0        0  0  0 |   | R |
  | G' |     |      0        0        0  0  0 |   | G |

  | A' |     | 0.2125   0.7154   0.0721  0  0 |   | A |
  | 1  |     |      0        0        0  0  1 |   | 1 |

(http://www.w3.org/TR/2011/REC-SVG11-20110816/filters.html#feColorMatrixElement)

This doesn't affect luminance masking (which depends only on the
resulting alpha channel), but other color filter users may care
about all color components.

1a4fb70c8a Moving 4 SkImageFilter derived classes from blink to skia 
There were 4 classes in blink that derived from SkImageFilter :
- TileImageFilter -> SkTileImageFilter
- OffsetImageFilter -> SkOffsetImageFilter (already existed)
- FloodImageFilter -> SkFloodImageFilter
- CompositeImageFilter -> SkCompositeImageFilter

All functions were copied as is, without modification (except for warnings fixes), except for the offset filter, which was merged into the existing SkOffsetImageFilter class, as a special case when a crop rect is provided. Since the names won't clash with the names in blink, it should be easy to integrate them in blink later and fix issues, if needed.

GM:lumamode will need rebaselining after landing this.

---

  In order to use CSS luminance masking, we need to be able to create an
  instance of SkLumaXfermode which can receive a kSrcOver mode, and applies
  that mode after converting the source using the luminance-to-alpha

4b681bc95b Fixed issues found by fuzzer 
Last week, the fuzzer found a few numerical issue with filters and I had written some fixes for them. Here are the fixes with some unit tests.

For senorblanco : So I figured out what was asserting when we'd get a 0 width "result" in SkBicubicImageFilter::onFilterImage(). Basically, if the "result" SkBitmap object calls SkBitmap::setConfig() with "width" and/or "height" set to 0, then the SkBitmap object will call SkBitmap::reset(), making the SkBitmap object's config invalid. At this point, calling SkBitmap::getAddr32() will assert, even without attempting to dereference the data pointer, because the SkBitmap's config is invalid. If height is valid, but width is 0, then this call to SkBitmap::getAddr32() happens directly in SkBicubicImageFilter::onFilterImage() a few lines lower and asserts right away.

fbaea53366 In image filters, apply the CTM and offset to the crop rect. This is necessary to compensate for both clipping applied by the compositor (communicated via the CTM) and for cropping applied in upstream image filters (communicated via the offset). This requires a few ugly conversions, since the crop rect is an SkIRect, and the ctm is an SkMatrix. 
I also had to offset the matrix passed to filter evaluation by drawSprite() and internalDrawBitmap() by the primitive position. This is the same offset that is applied when drawing the primitive, to compensate for the internal saveLayer().

Also apply the total matrix to the filter params in asNewEffect(), so that (for example) lighting params are offset by both the compositor clipping and upstream crop rects.

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

outside of tests. Consequently, this moves SkComposeImageFilter from
SkTestImageFilters.{h, cpp} into its own {.h, .cpp} files.
