writing text to image

[unitycoder]

someone asked about adding text feature, like in regular painting programs.
i don't think there is any simple way to do that, some ideas here:

• create text tool using UI text, then create rendertexture from that text (with transparent background), then use that as a custom brush to splat into image
• create ready custom brushes for each a-z character, then when user types text, splat those brushes into texture (gets complicated if need to support all characters)

and some info, here the custombrush stamping happens:
