    Reland "Make ANGLE program version only dependent on data that matters"

This is a reland of commit c303758fbc8d23266be578fae246e5687656b4c6

Changes made on top of original commit
1. Enable execution permission on python script
program_serialize_data_version.py
2. Remove unused list in libGLESv2.gni
3. In angle/BUILD.gn, change file path from
"relative to angle_root", to "relative to root_build_dir",
so that inside the script program_serialize_data_version.py,
we don't have to find the absolute path of the code files for
hashing.

Original change's description

> This change introduces a new variable ANGLE_PROGRAM_VERSION
> to track the version of ANGLE source files that affect shader
> program serialization/deserialization. This change include more
> source files than necessary, to serve the purpose of a conservative
> jumping off point. We will narrow down the list of files for
> ANGLE_PROGRAM_VERSION hash generation in the future.

> Add a new script program_serialize_data_version.py that will
> be triggered during the build when the related source files changed.
> The script will generate a hash and the hash size from the related
> source files. In program serialization/deserialization and cache
> key generation, we will use this hash value instead of the entire
> ANGLE git hash. When the hash value changed, we know that the
> related source files changed, and we should invalidate the program
> cache and re-generate the blob cache / program binary.

  • 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, 3.0 and 3.1 to Vulkan, desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Future plans include ES 3.2, translation to Metal and MacOS, Chrome OS, and Fuchsia support.

    ANGLE v1.0.772 was certified compliant by passing the OpenGL ES 2.0.3 conformance tests in October 2011.

    ANGLE has received the following certifications with the Vulkan backend:

    • OpenGL ES 2.0: ANGLE 2.1.0.d46e2fb1e341 (Nov, 2019)
    • OpenGL ES 3.0: ANGLE 2.1.0.f18ff947360d (Feb, 2020)
    • OpenGL ES 3.1: ANGLE 2.1.0.f5dace0f1e57 (Jul, 2020)

    ANGLE also provides an implementation of the EGL 1.5 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, Vulkan GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
