glIsVertexArray — determine if a name corresponds to a vertex array object
GLboolean glIsVertexArray(GLuint array);
glIsVertexArray returns GL_TRUE if array is currently the name of a renderbuffer
object. If renderbuffer is zero, or if array is not the name of a renderbuffer object, or if an error
occurs, glIsVertexArray returns GL_FALSE. If array is a name returned by
glGenVertexArrays, by that has not yet been bound through a call to
glBindVertexArray, then the name is not a vertex array object and
glIsVertexArray returns GL_FALSE.
