camera follow with deadzone and high zoom no longer smooth on v3.85.0 Beta 2

[Antriel]

Demo: https://phaser.io/sandbox/5rxAdUsy It's jittery in 85 beta 2, smooth before. Happens because of https://github.com/phaserjs/phaser/commit/26d85978d2494310c95760020ea62dca8b8b122a I think. Now the values jump a whole pixel, and then it smoothly follows to align. Before it smoothly followed constantly, as there was no rounding happening.

For internal use only

To resolve the jittery camera follow issue in v3.85.0 Beta 2, modify the Camera.preRender method in src/cameras/2d/Camera.js. Specifically, remove or adjust the Math.floor application to the scroll factor when rounding is enabled. This change will revert the behavior to smooth following without pixel rounding. Example modification:

// src/cameras/2d/Camera.js
preRender: function () {
    // Remove or adjust this line
    // this.scrollX = Math.floor(this.scrollX);
    // this.scrollY = Math.floor(this.scrollY);
    // Add smooth following logic here if needed
}
