…ortStream` class, and remove the `PDFDataRangeTransport.prototype.onDataProgress` method This is consistent with the other `BasePDFStream` implementations, and simplifies the API surface of the `PDFDataRangeTransport` class (note the changes in the viewer). Given that the `onDataProgress` method was changed to a no-op this won't affect third-party users, assuming there even are any since this code was written specifically for the Firefox PDF Viewer.
After https://bugzilla.mozilla.org/show_bug.cgi?id=1985121 this functionality is now guaranteed to be available in Firefox. Unfortunately general browser support is still somewhat lacking; see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/sumPrecise#browser_compatibility Also, while unrelated, use the `MathClamp` helper in the `applyOpacity` function.
