limits property

@override DeviceLimits get limits

inner's limits, with what a removed feature takes along: the compute limits without compute, one sample without offscreenMultisample, no views without multiview.

Implementation

@override
DeviceLimits get limits {
  final l = inner.limits;
  final map = l.toMap();
  final noCompute = _off(DeviceFeature.compute);
