Image and texture size limit

Different hardware has different limits for the size of images and textures.

So I have two questions regarding the texture size limit in Sailfish OS:

  1. What are the texture size limits for the currently available devices?
  2. Is there a Qt or Sailfish OS function to dynamically determine the image size (and/or dimensions) limit of the current device the app is running on? And is this way of determination compatible with Jolla Harbour?
    • If there is no such way: Do I need to hardcode the size limits for all devices? And if yes: How to determine the current device type (on a Harbour compatible way)?

Image and texture size limit

Different Since different hardware has different limits for the size of images and textures I am looking for a method to determine this limits. With 'texture size limit' I mean the actually supported dimensions an image/texture can have so that the device's hardware (GPU) and software is able to render it.

So for example some devices are supporting 1024x1024 textures and other support 4096x4096 textures.
