2575f317d3 Revert of Add tokens and entry points for KHR_blend_equation_advanced (patchset #3 id:40001 of https://codereview.chromium.org/1039693004/)
Reason for revert:
We're getting repeated crashes since this CL landed when we try to evaluate a roll into Chrome on our bots. (https://uberchromegw.corp.google.com/i/client.skia/builders/Linux%20Tests/builds/1902)

Our initial reflex is to put a #if 0 around this code (just like the immediately following lines 334-338 in GrGLInterface.cpp), but the error isn't what the GPU team expected to see if that was all we needed, so we're reverting now and asking you to resubmit tomorrow after running more thorough tests.

30bc88ccd5 Refactor SkGLContext to be actually extendable
Refactor SkGLContext to be actually extendable. Before, non-trivial subclass
would need to destroy the GL connection upon running the destructor. However,
the base class would run GL commands in its own destructor (with destroyed GL
connection)

Refactor so that SkGLContext subclass object creation is completely done by
the factory function. If the factory function returns a non-NULL ptr, it means the context
is usable.

The destruction is done with the destructor instead of virtual function called
upon destruction. Make the destructors not to call virtual functions, for
clarity.

Remove custom 1x1 FBO setup code from the base class. It appears not to be used
anymore.

9e61bb7815 Make the Sk GL context class an abstract base class
Make the Sk GL context class, SkGLNativeContext, an abstract base class. Before,
it depended on ifdefs to implement the platform dependent polymorphism.  Move
the logic to subclasses of the various platform implementations.

This a step to enable Skia embedders to compile dm and bench_pictures. The
concrete goal is to support running these test apps with Chromium command buffer.

With this change, Chromium can implement its own version of SkGLNativeContext
that uses command buffer, and host the implementation in its own repository.

Implements the above by renaming the SkGLContextHelper to SkGLContext and
removing the unneeded SkGLNativeContext. Also removes
SkGLNativeContext::AutoRestoreContext functionality, it appeared to be unused:
no use in Skia code, and no tests.

c8f5204667 Incorporate glStencilThenCover* nvpr methods
Adds the glStencilThenCover* nvpr methods to GrGLInterface and starts
using them. When drawing multible paths, this will make it so we only
have to send the index/transform data once. It will also allow the
driver to save time internally.

The glStencilThenCover* methods are a newer addition, so they aren't
available on every driver. In the event that they are not present, we
emulate them using the existing glStencil*/glCover* methods.

32b9a3b02e Add functions to support NV_path_rendering in OpenGL ES
Add OpenGL ES extension functions needed to support NV_path_rendering in OpenGL
ES.

The added glProgramPathFragmentInputGenNV call is defined in NV_path_rendering
revision 30, similar to following:

    Append to the end of the "Shader Inputs" subsection of Section 3.12.2
    "Shader Execution":

    The command

        void ProgramPathFragmentInputGenNV(uint program,
                                           int location,
                                           enum genMode,
                                           int components,
                                           const float *coeffs);

    controls how a user-defined (non-built-in) fragment input of a
    GLSL program object is computed for fragment shading operations that
    occur as a result of CoverFillPathNV or CoverStrokePathNV.

    /program/ names a GLSL program object.  If /program/ has not been
    successfully linked, the error INVALID_OPERATION is generated.

    The given fragment input generation state is loaded into the fragment
    input variable location identified by /location/.  This location
    is a value returned either by GetProgramResourceLocation with a
    /programInterface/ of FRAGMENT_INPUT_NV and a given fragment shader
    input variable name or by GetProgramResourceiv with FRAGMENT_INPUT_NV
    for the /programInterface/ and LOCATION for the property for a given
    fragment input resource index.

    ....

glProgramPathFragmentInputGenNV will be used instead of glPathTexGen,
because the latter depends on fixed function pipeline that is not
exposed in ES.

Also add glGetProgramResourceLocation from OpenGL 4.3 or
ARB_program_interface_query.

Also add FRAGMENT_INPUT define to be used with glGetProgramResourceLocation.

The added functions are not used yet, but they're needed when implementing
NV_path_rendering support for OpenGL ES. They can also be used on OpenGL.

Remove uncalled NV_path_rendering functions, so they do not cause confusion
or take space in the interface definition. The ones that are later used
can be re-added when needed.

Remove definitions NV_path_rendering that are for NV_path_rendering function
parameters that are not used. The ones that are later used
can be re-added when needed.

9245b7ee76 When performing offscreen rendering on windows, attempt to use a pbuffer context.
A pbuffer context is less likely to have a blocking SwapBuffers (due to vsync).

80549fcdd5 Support using OpenGL ES context on desktop
Support using OpenGL ES context on desktop for unix and Android platforms. This
is mainly useful in development.

Add --gpuAPI flag to gm, dm, bench, bench_pictures and render_pictures. The
possible parameters for the flag are "gl" and "gles".

4a995dfff2 Add functions to support NV_path_rendering in OpenGL ES
Add OpenGL ES extension functions needed to support NV_path_rendering in OpenGL
ES.

The added glProgramPathFragmentInputGenNV call is defined in NV_path_rendering
revision 30, similar to following:

    Append to the end of the "Shader Inputs" subsection of Section 3.12.2
    "Shader Execution":

    The command

        void ProgramPathFragmentInputGenNV(uint program,
                                           int location,
                                           enum genMode,
                                           int components,
                                           const float *coeffs);

    controls how a user-defined (non-built-in) fragment input of a
    GLSL program object is computed for fragment shading operations that
    occur as a result of CoverFillPathNV or CoverStrokePathNV.

    /program/ names a GLSL program object.  If /program/ has not been
    successfully linked, the error INVALID_OPERATION is generated.

    The given fragment input generation state is loaded into the fragment
    input variable location identified by /location/.  This location
    is a value returned either by GetProgramResourceLocation with a
    /programInterface/ of FRAGMENT_INPUT_NV and a given fragment shader
    input variable name or by GetProgramResourceiv with FRAGMENT_INPUT_NV
    for the /programInterface/ and LOCATION for the property for a given
    fragment input resource index.

    ....

glProgramPathFragmentInputGenNV will be used instead of glPathTexGen,
because the latter depends on fixed function pipeline that is not
exposed in ES.

Also add glGetProgramResourceLocation from OpenGL 4.3 or
ARB_program_interface_query.

Also add FRAGMENT_INPUT define to be used with glGetProgramResourceLocation.

The added functions are not used yet, but they're needed when implementing
NV_path_rendering support for OpenGL ES. They can also be used on OpenGL.

Remove uncalled NV_path_rendering functions, so they do not cause confusion
or take space in the interface definition. The ones that are later used
can be re-added when needed.

Remove definitions NV_path_rendering that are for NV_path_rendering function
parameters that are not used. The ones that are later used
can be re-added when needed.
