Continuously update min/max within canvas extent

Description

It would be great if there was a checkbox to "keep min/max values synchronised to canvas extents" for the min/max values of raster images. If the map was moved, this would make QGIS load new min/max values for the style color ramp and refresh accordingly.

This would greatly support exploration of DEM data and maybe more.

Examples of similar features:
"auto-exposure" in https://tangrams.github.io/heightmapper/
"Instant brightness, contrast and gamma correction" in https://www.youtube.com/watch?v=DR8l-0WajTw

Hi, it seems it's already in master :)
you have options in style options / "min/max value settings" / "Statistics extents" then choose "current canvas"
Nice feature indeed
