343382e3ac fix fuzz test that exceeds numeric limit
The extreme values here exceed an internal test that expects
computed numbers to be less than MAX_FLT. Use MAX_DBL instead.

3f0753d3ec fix fuzz bugs
Detect more places where the pathops numerics cause numbers
to become nearly identical and subsequently fail. These tests
have extreme inputs and cannot succeed.

Also remove the expectSuccess parameter from PathOpsDebug
and check instead in the test framework.

d0e402f999 Make container classes in SkTemplates.h more consistent
Ensures that ".get()" always returns null when a container is empty.
Also ensures consistent assert behavior for array counts.

There are still differences in that the malloc variants take a size_t
and the arrays take an int, and that SkAutoSTMalloc defaults to the
stack-allocated buffer wheras the other containers default to null.

93f66bc3af Apply canonicalizations to path GrShapes.
The following canonicalizations of path-backed GrShapes are added:

*convex shapes are stored with even/odd (or inv even/odd) fill.

*filled paths are closed.

*dashed paths ignore inverseness of the fill

This will improve the results of queries about the geometry that will be added in a future change.

875e13ca09 Simplify mask/clip intersection, making sure to explicitly check for an empty mask.
Previously we were only asserting the mask wasn't empty, which isn't necessarily true when we're given pathological float coordinates like +Inf or NaN.

A local run of nanobench --match text_ was not able to show this is faster or slower.

This patch fixed this first Chrome bug on my desktop, and the second is probably a dupe.

8811e40850 Refactoring of GPU NormalMap handling out into its own class.
The purpose of this change is to refactor the handling of normal maps out of SkLightingShader, laying the groundwork to eventually allow for multiple normal sources.

What this CL includes:

- Created a new 'NormalMapFP', out of the existing normal map reading behavior in LightingFP.

- Encapsulates this new fragment processor on a new class NormalMapSource.

- Created a NormalSource abstraction that will interface with SkLightingShader.

- Adapted SkLightingShader to use the normals from its NormalSource field ON THE GPU SIDE. No changes done to the CPU side yet.

a7d1e2a57a Refactoring of GPU NormalMap handling out into its own class.
The purpose of this change is to refactor the handling of normal maps out of SkLightingShader, laying the groundwork to eventually allow for multiple normal sources.

What this CL includes:

- Created a new 'NormalMapFP', out of the existing normal map reading behavior in LightingFP.

- Encapsulates this new fragment processor on a new class NormalMapSource.

- Created a NormalSource abstraction that will interface with SkLightingShader.

- Adapted SkLightingShader to use the normals from its NormalSource field ON THE GPU SIDE. No changes done to the CPU side yet.

Reason for revert:
Breaking build and deps roll. Need to move include of SkBitmapProcShader in SkLightingShader.cpp from gpu include list to general list.
