1. A method of rendering a symbol with non-linear scaling, the symbol comprising one or more elements, comprising: receiving a scaling instruction to scale the symbol, the scaling instruction including at least one scaling factor; determining, using a processor, whether to exclude one or more elements of the symbol from the scaling factor to be applied to the symbol, wherein a determination to exclude one or more elements is based on whether an element is tagged as being non-scalable by a user through a graphical user interface; and rendering the symbol on a canvas with non-linear scaling, such that the elements of the symbol that are determined to be tagged are not scaled according to the at least one scaling factor, wherein rendering comprises: specifying an anchor point for an element that is tagged as being non-scalable, wherein the anchor point determines a point of reference for the non-scalable element; and rendering the symbol as a function of a point P of the symbol, wherein P is the point to be transformed, the anchor point, and one or more scaling factors.
