Hello!

I was just doing some early experiments with glMultiDrawElementsIndirect, and was surprised to find that it only supports a client-side java.nio.Buffer as the argument for the "command list" (the "indirect" argument in the spec), rather than also allowing a long in order to use a buffer object bound to GL_DRAW_INDIRECT_BUFFER. Conversely, I also found that glMultiDrawArraysIndirect only supports a long to use said bound buffer object, but does *not* support a client-side Buffer instead, even though the C function does support using client-side memory, just like glMultiDrawElementsIndirect does.

Is this some mere oversight, or is there some thought behind it?
