+/** Make a PDF shader for the passed SkShader. If the SkShader is invalid in
+ *  some way, returns nullptr.
+ *
+ *  In PDF parlance, this is a pattern, used in place of a color when the
+ *  pattern color space is selected.
+ *
+ *  May cache the shader in the document for later re-use.  If this function is
+ *  called again with an equivalent shader,  a new reference to the cached pdf
+ *  shader may be returned.
+ *
+ *  @param doc         The parent document, must be non-null.
+ *  @param shader      The SkShader to emulate.
+ *  @param ctm         The current transform matrix. (PDF shaders are absolutely
+ *                     positioned, relative to where the page is drawn.)
+ *  @param surfaceBBox The bounding box of the drawing surface (with matrix
+ *                     already applied).
+ *  @param paintColor  Color+Alpha of the paint.  Color is usually ignored,
+ *                     unless it is a alpha shader.
