fix T53839: better default for curve resolution in abc import

Authored by Philipp Oeser (lichtwerk) on Jan 30 2018, 5:17 PM.



rB5bdbc88ab81891eff0 introduced a user property for curve resolution.
When this is not set (e.g. from other software) imported curves defaulted to a resolution of 1.
This is now changed to a resolution of 12 (matching blenders default for new curves)

Also see e12c31100. Guessing for default values is a tricky thing, especially since Alembic doesn't seem to have a standardised property for the curve resolution (I'm gladly proven wrong on this one). Having resolu=12 is fine for a simple case like T53839, but brings down Blender to a crawl when importing animated hair from another package.

Hi @Sybren A. Stüvel (sybren) , seeing the wider scope (case of hair), I guess current behaviour (default resolution of 1) seems indeed the wiser choice... user can always up the resolution by hand...
Will abandon this then and also archive T53839...
