------------------------------------------------------------------
I made an attempt to remove the two "do things that trigger a
ProfileDataException" calls and now rendering took 3000 seconds instead of 6000
seconds on my machine. However we can't remove these calls. Maybe we could do
some caching to avoid doing these checks multiple times.
According to the profiler, most time is lost in
{{PDColorSpace.toRGBImageAWT()}} when {{new ComponentColorModel}} is called.
