* Hopefully make singularity shader warping resolution-invariant This may or may not fix intensity issues * Fix singularity 'zero velocity' check It got stuck in a corner. Twice. I really thought I'd fixed that. * Make it easier to move around various power stuff by shrinking their AABBs a little and making singulo generator a circle * Changes to some machine prototypes to reduce duplication of collision changes (#1) * Changes to some machine prototypes to reduce duplication of collision changes * BaseMachine.BaseMachineUnpowered -> BaseMachine.BaseMachinePowered
