From 7f2da7bb878813817efab0eb01bbf274065ef6c6 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Tue, 30 Aug 2011 03:41:38 +0200
Subject: GLSL DataArray/Handler: Remove ShaderState state and pass it through:
ShaderState.getShaderState(gl)
This removes the dependency of a GLSL GLDataArray object to a specific ShaderState
and enables sharing of this VBO data, i.e. via a shared context.
Test: TestSharedContextVBOES2NEWT
