Internal __glSet the background color of the graphics context, default is [[Color.ExcaliburBlue]]
Access the debug drawing api
Enable smoothed drawing (also known as anti-aliasing), by default false
Snaps all drawings to the nearest pixel truncated down, by default false
Excalibur will automatically sort draw calls by z and priority for maximal draw performance, this can disrupt a specific desired painter order.
To force a specific draw call order, use [[ExcaliburGraphicsContext.z]]
By default useDrawSorting is true, to opt out set this to false
Gets or sets the material to be used in the current context's drawings
This allows customs shaders to be used but draw calls are no longer batched by default.

Sets the opacity of the current [[Graphic]] being drawn, default is 1

Set the current z context for the graphics context. Draw calls issued to the context will use this z to inform their sort order.
Note it is important to all [[ExcaliburGraphicsContext.save]] and [[ExcaliburGraphicsContext.restore]] when modifying state.

Add a post processor to the graphics context
Post processors are run in the order they were added.
Checks the underlying webgl implementation if the requested internal resolution is supported
Creates and initializes the material which compiles the internal shader
Material
Draw an image to the Excalibur Graphics context at an x and y coordinate using the images width and height
Draw an image to the Excalibur Graphics context at an x and y coordinate with a specific width and height
Draw an image to the Excalibur Graphics context specifying the source image coordinates (sx, sy, swidth, sheight) and to a specific destination on the context (dx, dy, dwidth, dheight)
Optional swidth: numberOptional sheight: numberOptional dx: numberOptional dy: numberOptional dwidth: numberOptional dheight: numberGets the current transform
Multiplies the current transform by a matrix
Remove a specific post processor from the graphics context
Update the context with the current viewport dimensions (used in resizing)
Meant for internal use only. Access the internal context at your own risk and no guarantees this will exist in the future.
