Code Review
This pull request corrects a test setup by changing the default test case and extending CpuSdfCanvas to support different pixel formats. A new method _loadR32FloatSdfImage is added to generate R32F textures, and the widget initialization logic is updated to select the appropriate image loading method based on the targetFormat. My review includes suggestions to improve the robustness of the new switch statement, fix a potential bug in the distance field calculation, and reduce code duplication.

This function is very similar to _loadRGBA32FloatSdfImage. There's a lot of duplicated code for setting up dimensions, calculating the signed distance field, and decoding the image. To improve maintainability and reduce redundancy, consider refactoring these two methods into a single one that takes the pixel format as a parameter and handles the differences internally. This would also make it easier to fix the calculation bug mentioned in the other comment in one place.

flutter@d57f6f8 had a merge conflict that I resolved incorrectly.
