TypeError: undefined is not a function error for iOS devices with Retina displays on 1.18.3

Describe the bug The same error that was described in issue https://github.com/matteobruni/tsparticles/issues/84 is still occurring on version 1.18.3. Desktop (including macOS with Retina display) and Android browsers seem to behave correctly, but iPhone and iPad on both Chrome and Safari will show the error exactly on this line https://github.com/matteobruni/tsparticles/blob/7784898e703dc04ae5b7cf7d69a9fb18baece16c/core/main/src/Core/Retina.ts#L51-L56

To Reproduce Steps to reproduce the behavior:

1. create a react app that imports react-tsparticles@1.18.3
2. copy the particle options from this example https://codepen.io/matteobruni/pen/BaoZBZy
3. start a development server
4. access the development server from an iOS device
5. see the error

Expected behavior The polygon mask particle effect should be correctly displayed

Screenshots

Smartphone (please complete the following information):

• Device: iPhone, iPad
• OS: iOS 13
• Browser Safari, Chrome

Additional context As you can see from the screenshot, I have tested from both the template (manually updated the package to be 1.18.3) app and the website I was working on (made with Gatsby), on the same package version. I was only able to test this using react. Additionally, the web application that is deployed on a remote server is showing the same issue as well, albeit with a white blank screen right before the particle load instead of any error messages.

Yes, it’s all working now.

Thank you very much!
