RTL direction support for language as (Arabic).

[SamiAziz]

Hello @Hufe921 ,

I would like to thank you for this great project.

I need help in how to implement RTL direction to write in Arabic language.

version
0.9.64

What is expected?
That the text start from right-to-left, and the cursor be at the end of last word in the left, also wrap word in new line if get to the edge of the paper.

What is actually happening?

Additional comments
I Added Arabic charsets to LETTER_CLASS in (canvas-editor) file as shown down, but it didn't work.
