replace the texture level hack used in radeon/r200 to allow larger textures with different methods to calculate the announced maximum texture sizes. Default is still the same (that is, radeon/r200 default to not announce anything which might not fit, i830/i915 default to 1 texture must fit). Bug #5785.
