//! This example shows how to configure Multi-Sample Anti-Aliasing. Setting the sample count higher
|
|
//! will result in smoother edges, but it will also increase the cost to render those edges. The
|
|
//! range should generally be somewhere between 1 (no multi sampling, but cheap) to 8 (crisp but
|
|
//! expensive).
|
|
//! Note that web currently only supports 1 or 4 samples.
