Agg enters an infinite loop if you give it points that are NaN, due to converting the values to fixed-point integers, and then oscillating between the large values that result from that conversion. NaN values may be introduced after transforming the input, so we need to trim those after transformation. This matches what is done in normal paths.

PR summary
Agg enters an infinite loop if you give it points that are NaN, due to converting the values to fixed-point integers, and then oscillating between the large values that result from that conversion.
NaN values may be introduced after transforming the input, so we need to trim those after transformation. This matches what is done in normal paths.
The test itself is mostly a smoketest to ensure we don't crash.
Closes #26765
