==================

Accidentally Closes #1815

Fix tiling artifact that can appear in standard dpi screens, this is caused by seams in the geometry that may not fall on an actual screen pixel causing a visible gap between the tiles to the background

The solution is to remove unnecessary scaling in the graphics pipeline, a UV bodge factor to keep the pixels from bleeding to the next texture in power of 2, and optimizing the camera update and positioning.

Changes:

• Removes unnecessary scaling in graphics pipeline
• Adds UV bodge factor to combat sampling bleed in power of 2 textures
• Fixes a bug with the screen/world coordinate mapping
• Moves camera update to the end of the update cycle, which reduces jitter mentioned in lockToActor jitter on large velocities — Camera.update() should be called onPostUpdate #1815 and also helps ensure the camera is in an ideal screen position after all updates and before the draw

TODO before merge

• Tests
• Code cleanup (avoid passing engine down to the renderer)
