Value
CairoScaledFont

This function never returns NULL
. If memory cannot be allocated, a
special "nil" CairoScaledFont
object will be returned on which
cairoScaledFontStatus
returns CAIRO_STATUS_NO_MEMORY
. Using
this nil object will cause its error state to propagate to other
objects it is passed to, (for example, calling
cairoSetScaledFont
with a nil font will trigger an error that
will shutdown the Cairo
object).
