| font | the font to query. |
| text | text to calculate, in UTF-8 encoding. |
| w | will be filled with width, in pixels, on return. |
| h | will be filled with height, in pixels, on return. |
Returns 0 if successful, -1 on error.
This will report the width and height, in pixels, of the space that the specified string will take to fully render.
