eglfs mouse cursor rendered incorrectly

Launch an app with eglfs on any device (or even X11) with the mouse enabled. The pointer image looks slightly incorrect, it's as if the cursor image was slightly skewed or scaled. (texture coordinate problem?)

Reproducible both on DRIVE CX with eglfs_kms_egldevice and on desktop using eglfs_x11.

The cursor is nice and clear with the current 5.6 branch.
