Add ability to use text markup on more file types

[#1]

Description - We want to be able to use the Text Markup tool on more file types.

Why is this feature important to you - We use the Text Markup frequently on multiple proofs and want to use it on more file types.

How would you like the feature to work - Exactly like it currently does, but on more file types (.png, .jpg, .txt, etc).

Current Behaviour - This tool only seems to work on .docx and .pdf documents currently.

I can upload PNG files and mark them up, can you elaborate?

[#3]

I am referring specifically to the "select text" markup tool, which I have found only appears on .docx and .pdf files. It doesn't even show up on .txt files, which seems wrong.

You will not be able to read any text on raster image formats within the proofing viewer, that's not just a limitation with Workfront but it speaks to the nature of those filetypes.

For text specifically you might have better luck using RTF instead of TXT.
