Subject: [PATCH] fix(scanner-effect): lower default DPI in
 ScannerEffectRequest (#4565)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description of Changes

On High preset the Scanner-effect request was blocked on default since
max DPI is 500. This meant if users **tried** to use Scannereffect on
default DPI limit, and default ScannerEffect setting then they would get
error. This update lowers default high preset's DPI to 300 so that is
under the default limit.
