    Prepare for -Wimplicit-fallthrough in ANGLE.

Disable the warning for flex-generated output, which contains
lots of intentional fallthrough.

Fixes a bug where GL_SAMPLE_ALPHA_TO_ONE_EXT would fall through
to GL_COVERAGE_MODULATION_CHROMIUM and hence behave like that.

Fixes a bug in the D3D9 state management where invalidating
DIRTY_BIT_POLYGON_OFFSET would also invalidate the stencil bits.

One somewhat common incorrect pattern in ANGLE is nested switch
statements that look like so:

  switch (a) {
    case a1:
      switch (b) {
        case b1:
          ...
          break;
      }
    case a2:
      ...
  }

The assumption here seems to be that the breakk exits the outer
case (here a1), while it in fact only exits the inner switch,
so that we fall through to a2.  In most places, I fixed this
by adding an explicit `break` after the inner switch.

This fixes a bug wher GL_PATH_JOIN_STYLE_CHROMIUM would fall through to
GL_PATH_MITER_LIMIT_CHROMIUM in validation (but since the join style
enum is always > 0, this happened to not have an effect in practice).

This also fixes 87 bugs in GetLoadFunctionsMap() where invalid
values would previously return an unrelated function map instead
of the empty load function map.

  • ANGLE - Almost Native Graphics Layer Engine

    The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

    ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

    ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

    Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
