* cannot return min max if triangular mesh does not exist * only create QgsRenderedLayerStatistics if values changed to prevent loop in rendering * this was set from two places, remove it from here * Revert "this was set from two places, remove it from here" This reverts commit 5d8fbcc321330f1054e5e07cad2ee70c0f9aa661. * add test case for not existing triangular mesh * only emit signals here, everything else is handled in renderer creation (avoids double rendering of the mesh layer) * while updating the widget the component signals need to be blocked * do not update render here * add const * 3D map should not update layer statistics * update renderer settings from here, signals are emitted from mesh layer * update test to simulate main canvas extent update * do rendering in single pass * emit renderer changed and remove emit of legendChanged
