Bug 1708224 - Make draw_perspective more resilient to NaNs. r?aosmond

### Beta/Release Uplift Approval Request
* **User impact if declined**: Linux users running SWGL get hangs in 89 as documented in bug 1714779, bug 1716160 and bug 1717089. We haven't been able to reproduce it locally and don't know the root cause yet so it's difficult to estimate the number of effected users.
* **Is this code covered by automated tests?**: No
* **Has the fix been verified in Nightly?**: Yes
* **Needs manual test from QE?**: No
* **If yes, steps to reproduce**:
* **List of other uplifts needed**: None
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: It's very low risk and has ridden the trains into 90. The change just adjusts things so that we handle NaNs better.
* **String changes made/needed**:

Status changed to 'Confirmed' because the bug affects multiple users.

[Olivier Tilloy (osomon)]

Quite possibly linked to https://bugzilla.mozilla.org/show_bug.cgi?id=1708224.

[Olivier Tilloy (osomon)]

If this is indeed the issue mentioned in that upstream bug report, then the 89.0.2 release candidate should fix it.

[Olivier Tilloy (osomon)]

Firefox 89.0.2 was published to all supported Ubuntu releases, so I'm tentatively marking this fixed. Please re-open if this isn't the case.
