HD Text is interpolated incorrectly on Render Dragon on odd number gui scale

When using an odd number gui scale (as shown in the debug info of betas/previews), the text is interpolated correctly if it is high res.

How to reproduce:

1. Install a high res font pack or use a special character like ŕ to get high res font
2. Type something in chat
3. Compare how it looks on odd vs even gui scale (use beta/preview to see gui scale)

Observed results:

The resolution of the text is different (looks interpolated) and there are sometime artifacts when on odd gui scale.

Expected results:

It should be same resolution as even scales and no artifacts when on odd scales.

 

I believe this is the root cause of MCPE-110767
