Remove resizeMode due to possible loss of performance

 !!! tip "Landscape × Portrait"
 
-    You generally do not need to specify an `aspectRatio`, as encantar.js uses a suitable default. When customizing this setting, pick standard values for landscape mode such as `16/9` or `4/3`. Pick such values even if mobile devices are expected to be in portrait mode. Using arbitrary numbers is discouraged and may produce unexpected results in different devices.
