Feature request: Add padding parameter

[ivanpopelyshev]

Subj, usually texture packer apps accept padding param between symbols so shader is easier to code, simple clamp() is not enough if I draw want to draw the letter with spacing, for example when i want to scale it

Thanks for awesome lib btw!

I'm sorry, but I didn't understand your example. Can you explain more clearly a use case where padding is required?

I had this picture, then I added extra clamping that fixed it.

But now i tried to reproduced it again, and it turned out I actually had mipmaps turned on :)

Never mind then.
