CLIENT_ALL_ATTRIB_BITS: constant -1 overflows gl.GLbitfield

[pwaller]

CLIENT_ALL_ATTRIB_BITS                        = -0x1

This is not compatible with a function call to gl.PushClientAttrib.

# gl.PushClientAttrib(gl.CLIENT_ALL_ATTRIB_BITS)
experiment.go:32: constant -1 overflows gl.GLbitfield

[banthar]

This can be solved by adding explicit type to those constants:

    CLIENT_ALL_ATTRIB_BITS                        GLbitfield = C.GL_CLIENT_ALL_ATTRIB_BITS

Unless, they are used somewhere else as different type.

Since the new method of generating the constants, this appears not to be an issue anymore.
