As discussed with @rouault on the mailing list, I found that when the WMS driver is provided with a fine resolution, a raster is attempted to be created that overflows GDALs 32-bit integer based dimensions.
This fix limits the generated resolution to a value that does not overflow the 32-bit integer value.
