* Add a script to build and install cairo
* Update gui tests for cairo 1.18.0
* update script to set env vars
* Make the script run with plain python
* Prefer the recently built one in pkg-config
* Skip the built if it's windows
* CI: build and install latest cairo
* CI: only run when cache is missed
* Disable compiling tests while building cairo
* update poetry lock file
* Display the cairo version when running pytest
* fixup
* tests: skip graphical test when cairo is old
* fix the path to find the pkgconfig files on linux
* set the LD_LIBRARY_PATH too
only then it'll work on linux
* fixup
* small fixup
* Move the script inside `.github/scripts` folder
* Make the minimum cairo version a constant
* Seperate setting env vars to a sperate step
this seem to have broken when cache is hit
* Add scene.replace() and use in ReplacementTransform
This replace method allows one mobject to take the place (that is,
the draw order) of another mobject.

* Prevent TransformMatchingTex from crashing when there is nothing to fade
Fixes#2845 and adds tests.
I originally tried to make FadeTransformPieces not crash if it was given two Mobjects with no submobjects, but I couldn't quite get that to work. This is probably the less invasive of a change.

* Update expectations after Tex change
* Address feedback
This makes FadeTransform::ghost_to more robust to receiving an empty target. It is currently unspecified what should happen, so how about just fading in place?
