1. One or more computer-readable storage media having executable instructions stored thereon, which, in response to execution by a processor of a computing device, provide the computing device with a drawing application that implements pressure sensitive stroke attributes to: receive input stroke data that includes path data defining a path of a stroke to be rendered on a display of the computing device and a plurality of pressure measurements along the path; map each of the plurality of pressure measurements along the path to respective attribute values for a pressure sensitive stroke attribute, wherein a first pressure measurement at a predefined level of pressure causes a first attribute value to be a default attribute value, and wherein a second pressure measurement above or below the predefined level of pressure causes a second attribute value to be either larger or smaller than the default attribute value; and cause the stroke to be rendered on the display in accordance with the respective attribute values of the pressure sensitive stroke attribute.
