1. A method, comprising:
displaying a first set of polygons of a shape having a first current size on a display of a computing device, wherein the first current size is associated with at least a first multiplier value for the first set of polygons;
receiving, at the computing device, an instruction to draw the shape having a second current size;
determining a second multiplier value for the shape using the computing device, wherein the second current size is associated with the second multiplier value;
determining whether retessellation is to be performed for the shape based on the first multiplier value and the second multiplier value;
after determining that retessellation is to be performed, determining a second set of polygons that tessellate the shape based on the second multiplier value using the computing device, wherein the second set of polygons comprises two or more polygons, and wherein the second set of polygons differs from the first set of polygons; and
displaying one or more polygons of the second set of polygons on the display.
