Essentially, this means to render transformed images, which, depending
on the given transformation, will have much lower quality than doing
vector transformations. While the existing interface was not directly
intended to work like this, since it produces coverage scanlines, it
could be possible to wrap image accessors around the data, but I am sure
this will involve some unwanted overhead. Coverage scanlines do not
contain color information, for this, you need a "span generator", for
text most likely generating a solid color. However, you would need to
combine all this to be able to wrap an image accessor around the result,
since they usually work in the same color space as the target surface.
Like I said in the beginning, quality may be greatly reduced depending
on the transformation, so I wonder if it's worth the trouble.

Best regards,
-Stephan
