glIsBuffer — determine if a name corresponds to a buffer object
GLboolean glIsBuffer(GLuint buffer);
glIsBuffer returns GL_TRUE if buffer is currently the name of a buffer object. If buffer is zero, or is a non-zero value that is not currently the name of a buffer object, or if an error occurs, glIsBuffer returns GL_FALSE.
A name returned by glGenBuffers, but not yet associated with a buffer object by calling glBindBuffer, is not the name of a buffer object.
