Window with a canvas that can be painted.
The Canvas provides access to both rendering and input functionallity, as the input must be tied to a window
A canvas represents a window with a width * height pixels.
There's also a scale variable that controls the integer scaling
and a clearColor that is applied to the whole canvas when it's cleared.

Gets the color from the this surface.
This operation can be perfomance intensive, so it might be worthwile
to either use getPixels to fetch multiple pixels at the same time or
to implement this operation on the application code.

Copies this surface into a new surface stored in RAM.
Gets the color from the this surface in an unsafe way.
Gets the color from the this surface in an unsafe way.
This operation is unsafe: reading a out of bounds pixel has undefined behavior.
You should only use this if the performance of getPixel and getPixels are not acceptable.
