This is enough to get all of the sample apps running on a conformant ES 3.1 implementation, such as ANGLE/Vk or NVidia's OpenGL ES Linux driver. Implements a new opengl::AdapterDiscoveryOptionsES subclass to specify its creation at adapter discovery time. Adds a "-b opengles" command-line flag to the code samples. Asserts on a call to glShaderStorageBlockBinding() on ES. Works around missing indexed draw buffers support by asserting when a non-0 color attachment is specified. Works around missing glClearTexSubImage() by asserting. :/ These will likely require front-end validation.
