There is a man page for PCFactorSetDropTolerance, the user's manual
discusses it, and the option is available in -help. I'm just pointing
out that this is fairly confusing. The manual also mentions
PCFactorDTSetReuseFill which does not currently exist.
There seems to be something available with -pc_type icc
-pc_factor_mat_solver_package bas, but this is actually undocumented so
I'm not concerned about whether or not it works.
