Support rendering text on a specified area in the image

[Neway6655]

Could you pls implement some more operations, like java.awt.Graphics2D's drawString method.

We are very appreciated if you can help to add this operation. Thanks!

Yes, I need it too!

Hi,
I will take a look but I remember that drawing string into an image with libvip is not as trivial as Graphics2D's library

[Xmonpl]

The syntax is similar, and it will certainly be more faster than using Graphics2D library i think.

work in progress, the main inconvenient is the pango library that I can't embed yet because it's the hell to build it from scratch (lots of deps and meson/ninja build system)
