view framework/TransformUserConfigurator.h @ 562:3c846b06c518 3.0-integration

When returning the frame that we have filled to, avoid accidentally reducing the frame number (making it appear we are less filled than we really are) when we had intended to round it up to the full requested amount. Fixes some unexpected double-playback in non-looping play-selection mode.
