This broke some games which relied on ESSL1-only extension macros not being defined in ESSL3 shaders. This change adds min/max version information to list of extensions so the preprocessor can conditionally expose extensions based on the shader language version, both via the extension name macros and the #extension directive.

Le Hoang Quyen dadd1986 2020-04-21T01:50:00 Implement GL_APPLE_clip_distance - Built-in variable gl_ClipDistance has been added to compiler. - Desktop GL: gl_ClipDistance is supported since GL 3.0. Enable/Disable each gl_ClipDistances[i] works out of the box via glEnable(). - Vulkan/Metal: Use uniform variable to control writing to each gl_ClipDistance. One bit flag controls one element in the gl_ClipDistance array. The writing to the disabled element in vertex shader will be ignored, and turned into zero assignment instead. - Direct3D/Mobile GL: Not implemented yet. - Added ClipDistanceTest to gl_tests and compiler unittests. - GL_APPLE_clip_distance is a subset of GL_EXT_clip_cull_distance, so GL_EXT_clip_cull_distance could be implemented in future if needed.

Yan 17b3c2f3 2019-10-14T14:13:59 Implement SamplerVideoWEBGL for WEBGL_video_texture extension on desktop WEBGL_video_texture is an extension that will improve uploading video frame to WebGL performance. (https://www.khronos.org/registry/webgl/extensions/proposals/WEBGL_video_texture/) This extension introduced a new texture type TEXTURE_VIDEO_IMAGE_WEBGL and a new sampler type samplerVideoWEBGL to sample it. In chromium implementation, TEXTURE_VIDEO_IMAGE_WEBGL maps to different native texture type based on platform. On desktop, it maps to GL_TEXTURE2D(Currently supported). On Android, it should map to GL_TEXTURE_EXTERNAL(TODO). SamplerVideoWEBGL needs to be mapped to sampler2D or samplerExternalOES according to TEXTURE_VIDEO_IMAGE_WEBGL implementation. This patch implements samplerVideoWEBGL in Angle to support WEBGL_video_texture on desktop. In this case, samplerVideoWEBGL should map to sampler2D.
