supportsOffscreenMsaa property

@override bool get supportsOffscreenMsaa

Whether a multisampled offscreen target is available at all.

Kept beside preferredSampleCount rather than folded into it: a device may report a count it can multisample with while still being unable to give the engine an offscreen target to use it on.

Implementation

@override
bool get supportsOffscreenMsaa => true;
