    app: update drawable when committing Warp tool
    
    Make sure to update the drawable after committing the Warp tool, if
    high-quality-preview is disabled, and we use a non-nearest sampler.
    
    Necessary after commit d928a80b7faf48f637315b89eb6107647ff9d05b.
    
    (cherry picked from commit 2da5cb562d24f18dc4b4140d3111f5a6ea13740c)
