Images of WebGL Tile Layer get resized

See original GitHub issue

Describe the bug With the current HEAD of the main branch (commit a788c9bd1ebc93761660b3c5c290b9fbd6c8d42f), images of WebGL TileLayer loaded with DataTile source are resized (stretched along the row or column direction) for some tile grids. That leads to distortions of the raster graphics and incorrect display of corresponding vector graphics.

I encountered this problem with the following tile grid:

This is the image at the top of the pyramid (zoom level 0):

This is the image one level below the top of the pyramid (zoom level 1):

One can clearly see that pixels are non-square in the first image and that the vector graphic (orange line) is displayed at the wrong spatial location.

The images display correctly with an earlier version of the app that uses Canvas tile layers of release v6.9.0.

Do you already know the timeline for the next release?

@hackermd - You can use the latest with npm install ol@dev. It has been a while since the last release, but nobody has gotten around to cutting a new one (summer for many).
