We need a simple canvas drawing widget that we will integrate as an drawing editor on one of our websites.
The <canvas> drawing widget must have the following characteristics:
Save and load XML of the drawings.
Free drawing tool.
Line drawing tool.
Square drawing tool.
Simple color palette.
Drag and Drop images from a box. (When dropped on the canvas, the image coordinates must become part of the XML that the widget will save/load.)
The contractor will receive a wireframe for the app.
