Add a new API for disabling antialiasing of shapes drawn by cairo. This is a hint and is not supported by all backends.
Store the antialiasing mode in the gstate and pass it to the backend for trapezoid rendering and for clipping.
Pass the antialiasing parameter down to the backend where appropriate.
Pass the antialiasing parameter down to the backend where appropriate.
Add support for A1 format trapezoid rendering, and remove the _create_mask_image function, creating a temporary image from memory we allocate and clear.
Support A1 masks to disable antialiasing using the RENDER extension when requested.
Support A1 masks to disable antialiasing using the RENDER extension when requested.
Blindly pass through the antialising parameter.
Add the antialiasing parameter but don't support it.
Add a test case and a reference image from the latest libpixman.
Add the new antialiasing disabling API to the docs.
Update progress on a parameter to disable antialiasing.
