Text Tool

[MarkE16]

Implement a new tool for entering text. See the Canvas Text Properties for drawing text.

There are several ways to go about this. The simplest way would be to allow a textbox to appear wherever the pointer is clicked and render the text when the enter key is pressed. However, like all pixels, once rendered, you cannot move the text.
The other way would be to not render the text at all and only keep track of the text's properties (e.g., x, y, width, height, content, font, size, layer), so that it's visible and can be moved. The only time to render the text would be when the canvas is being exported.
