Description Giuseppe Barbieri 2016-02-03 15:32:21 CET 
This binding:

gl4.glBindBuffer(GL_PARAMETER_BUFFER_ARB, bufferName[Buffer.PARAMETER]);

Fires the following exception:

Caused by: com.jogamp.opengl.GLException: GL_INVALID_ENUM​: Invalid binding target 0x80EE
	at jogamp.opengl.GLBufferStateTracker.checkTargetName(GLBufferStateTracker.java:174)
	at jogamp.opengl.GLBufferStateTracker.setBoundBufferObject(GLBufferStateTracker.java:189)

	at tests.gl_500.Gl_500_multi_draw_indirect_count_arb.initBuffer(Gl_500_multi_draw_indirect_count_arb.java:300)



GL_PARAMETER_BUFFER_ARB is a legal buffer binding

Actually the fix is pretty easy :p

GLBufferStateTracker needs to support ARB_indirect_parameters, 
i.e. checkTargetName(target) and getQueryName(target) 
need to recognize GL4.GL_PARAMETER_BUFFER_ARB.
