I wonder if it would be possible to introduce features into ThorVG that would allow for an efficient implementation of a text field.

What I miss is support for scenarios:

• I have the coordinates of the mouse cursor, I need to know the position of the text cursor (character index)
• I have the position of the text cursor, I need its coordinates

These cases can be reduced to:

• give me the maximum character index for a width limit (for given text in given style)
• give me the text width for a substring

I think this requires adding mechanisms to measure text without having to render it. Would there be a place for such functionality in the library? Or maybe it is possible to use existing mechanisms to achieve these goals?
