WebGLBindableName represents a GL 'name' (GLuint) that can be bound to part of the GL state machine. Similar code appeared in a number of classes that represent GL bindable names, such as WebGLBuffer, WebGLTexture, WebGLFramebuffer, etc. Cleanup to reduce copy-n-paste code that's needed for creating new objects for WebGL 2. --HG-- extra : source : ad7803e3daf5862099f62f24fdbc83639be1ed5a
