[1.6.4] resizing window

Hi,

is there any good way to resize Minecraft window during startup with mod? I am doing a little util that will save all recipes, and I need to resize window to render icons in desired size.

What I found to work:

Minecraft.getMinecraft().toggleFullscreen();
ObfuscationReflectionHelper.setPrivateValue(Minecraft.class, Minecraft.getMinecraft(), 160, "tempDisplayWidth", "field_71436_X");
ObfuscationReflectionHelper.setPrivateValue(Minecraft.class, Minecraft.getMinecraft(), 160, "tempDisplayHeight", "field_71435_Y");
Minecraft.getMinecraft().toggleFullscreen();

But I wonder, is it possible to achieve it without toggling fullscreen (causes annoying flashing)?

Thanks in advance.
