Set Sprites to Lowres?

On A500, Sprites are displayed Lowres just like the bitplane.. However on A1200 running Productivity 640x400 screenmode, Sprites are displayed in the WB screenmode.

How do we force Sprites to display in Lowres only?

See graphics/VideoControl(), in particular the VTAG_SPRITERESN tag:

Code:
        VTAG_SPRITERESN    [_SET        | _GET] -- set/get sprite resolution
                      (legal values are SPRITERESN_ECS/_140NS/_70NS/_35NS.
                       see graphics/view.h) (V39)

$dff106, bits 7-6 (00=ecs defaults, 01=lores, 10=hires, 11=shires).
Initialize custom registers with default OCS/ECS values: bplcon3 $106=$0c00, bplcon4 $010c=$0011, fmode $01fc=$0000. Adjust these for your needs.
