Subject: [PATCH] Use Image class' blend_rect method if Godot's version is
 3.2.2

https://github.com/godotengine/godot/issues/31124 has now been fixed in Godot 3.2.2-rc1, so we can use Image.blend_rect() instead of a custom method. This makes exporting large images and drawing with large brush sizes a lot faster.

Once Godot 3.2.2 stable is released, the custom blend_rect method will be completely removed.
