resolution	float	The resolution of the color range.
saturation	float	The saturation of the resulting colors.

Scrolling Camera

Roughly simulate a camera that follows the player around the level.

How to Use:

• Place the shader in the shaders folder and rename it colormapped.shader.
• Create a new level and set the camera bounds to be the size you want your scrolling camera to be.
• Make sure the camera bounds are completely outside of the actual level area.
• Place the camera bounds to the bottom-right so the player doesn't die for being off-screen.
• Use the level editor to create large enough levels to fulfill these requirements.

Known Issues:

• User interface elements will not be visible when playing like this.
• Most shaders are not compatible with the scrolling camera.
• The scrolling camera is global and cannot be turned off for specific levels.
• There are some issues with scrolling and it is not always reliable.
