Description
mapbox-gl-js version: 1.5
browser: Chrome
Steps to Trigger Behavior
When using a raster tile overlay, tile images are scaled in zoom ranges between two integers (if you zoom-out from level 10 to 9 for example, tiles from zoomlevel 10 are visible until you reach zoomlevel 9). Is there any option available to zoom in steps of 1, so if you scroll your mouse for zooming, factor 1 is used to zoom in/out? For vector tiles this isn't a problem, but for raster tiles it is desirable to zoom in steps of 1. Is this adjustable or is it a bug when using raster tiles?

Research direction
Start by reproducing the raster tile overlay behavior described for mapbox-gl-js 1.5 in Chrome, using the mouse wheel to zoom between levels 10 and 9. Read the zoom handling and raster tile rendering entry points to determine whether integer zoom steps are supported. Done means the issue is resolved with an available adjustment or a clearly scoped implementation plan.
