+ * <b>Why does DH often call GL methods twice? </b><br> 
+ * Once using the base {@link GL32} function and a second time using
+ * Minecraft's {@link GlStateManager}?<br><br>
+ * 
+ * <b>Answer: </b><br>
+ * Compatibility and robustness<br>
+ * In general all MC rendering should go through MC's {@link GlStateManager},
+ * however that isn't always the case.
+ * So, to prevent issues if a mod (or MC itself) calls a direct GL function
+ * instead of the {@link GlStateManager} wrapper, we need to be sure about what the actual
+ * set value is (whether setting or getting) and that MC knows what DH has done.
+ * This way whether a mod (or MC) is using the {@link GlStateManager} or direct GL calls,
+ * they should always have the correct value for anything DH has modified.
+ * <br><br>
+ * This may slow down some low end GPUs that are driver limited,
+ * however James would rather have slow correct rendering vs fast broken rendering.
