Change func names and parameter order to more closely follow OpenGL
ES/WebGL spec.
BufferData(target, usage, src) -> BufferData(target, src, usage)
GenBuffer -> CreateBuffer
GenFramebuffer -> CreateFramebuffer
GenRenderbuffer -> CreateRenderbuffer
GenTexture -> CreateTexture
Fix issue where glBoolean helper was returning inverted result.
Make Attrib.String() logic consistent with others (print value, not
struct).
Make internal code of GetUniformLocation the same as GetAttribLocation
and BindAttribLocation for consistency.
Resolves golang/go#10218.
