86f31f287e [svg] Fix filter effect subregion calculation
Somewhat subtle, but we were improperly handling the override of the
default subregion via the 'width' and 'height' <fe*> attributes.

Simple example: when specifying 'x' but not 'width', previously we
would use the overridden x (subregion.fLeft = boundaries.fLeft;), but
were not updating subregion.fRight based on the new fLeft value.

48fb05b81c [svg] Fix text object bounding box resolution
Two issues:

1) we are currently computing object bounding boxes using the
   RenderContext of the client resource, which can override presentation
   attributes

   -> introduce an OBBScope to capture not just the current OBB node but
      also its original RenderContext

2) text fragments must use the root <text> bounding box for OBB-relative
   units [1]

   -> update SkSVGTextFragment::renderText to not override the current
   OBBScope; this ensures we're using the root element scope for the
   whole text subtree

Tests filters-specular-01-f and filters-light-02-f should be passing

currently think the test is somewhat poorly written, so we are

these unwanted defaults are magically known to exist and removed

templates and apply these defaults to those instead.

bded42ab51 Split :tests into :test and :tests.
Split the :tests target into a :test target which contains the test
framework and :tests which collects all of the test cases. This allows
for all targets which define tests to depend on :test in order to define
tests, with :tests then depending on all targets which define tests. A
similar split should be considered for gms, samples, and benches.

We already had a function to compute the appropriate matrix, and since
we can share the functionality with other elements that establish a new
viewport (including svg, symbol, and a few others), this CL moves the
function to the SVG node base class.

Relevant test for images is struct-image-06.

e71f547302 [svg] Expand SkSVGIRI type
This CL adds a type enum to SkSVGIRI that will eventually be used to
distinguish between local fragments ('#frag-id'), non-local fragments
('/path/to/file.png') and data URIs ('data:image/png;base64,...').

To do so required a bit of refactoring of other types that previously
treated IRIs as basic strings. There are no functional changes in this
CL.

8eedcd2dea [svg] Partial implementation of feSpecularLighting
https://www.w3.org/TR/SVG11/filters.html#feSpecularLightingElement

Because a fair amount of functionality will be shared between
feSpecularLighting and feDiffuseLighting, this CL adds an intermediate
SkSVGFeLighting base class for common code.

The only light source type implemented in this CL is fePointLight, which
exercised by the filters-light-03 W3C test.

In preparation for text bounding box support, fission the actual

  - rename onRenderText -> onShapeText
  - introduce a ShapedTextCallback abstraction for consuming the result
    of text processing
  - relocate the final rendering step to a ShapedTextCallback impl
