TXFAFormScriptLimits Record
TXFAFormScriptLimits.Default supplies non-zero limits for every scripting resource
MaxScriptBytes, MaxOperations, MaxElapsedMilliseconds, MaxExpressionDepth, MaxArrayItems, MaxValueBytes and MaxInstanceOperations bound the common XFA layer
JavaScriptMemoryBytes, JavaScriptStackBytes and JavaScriptInterruptChecks map directly onto the QuickJS bridge runtime; the stack boundary also limits recursion
