Loads the next count bytes of the image. This will return TRUE if the data
was loaded successful, and FALSE if an error occurred. In the latter case,
the loader will be closed, and will not accept further writes. If FALSE is
returned, error will be set to an error from the RsvgError domain. Errors
from GIOErrorEnum are also possible.
