Better finish decal. DeCal is good and comfortable for most cases, and
trying to speed it up will kill the ease of use.

Then we can collect some other set of routines over time for more performance

It's not as friendly ;-)

If we move decal to packages/contrib, we can move the docs to the fpcdocs
dir ?
