Changing resolution of SpawnIcons?

Well, basically I want to make resolution of SpawnIcons better, so I can use them with at least 128x128 size. Of course, not only for myself, but for all players on server. Is there a way to do it?

	local 	recipeModel = vgui.Create( "SpawnIcon", recipeBg )
			recipeModel:SetModel([recipe]["recipeResultModel"] )
			recipeModel:SetSize( 128, 128 )

Code of spawnicon and screenshot of low-res icon. Thanks in advance :3
