Detailed Description

Defines higher level TFT graphics functionality.

The LT7683 chip can create multiple canvass for holding graphics. Callers can place graphics onto the canvass and they can use the graphics engine of the LT7683 chip to draw geometric shape. When ready, the caller can then signify which canvas is to be diplayed within the TFT window. The Canvas class provides a higher level interface to the LT7683 chip, provides methods for creating, managing, and using canvass.
