WIP: Add a temp framebuffer to control z-depth

The stroke is rendered to temporary framebuffer and then render again using fullscreenquad to add the z-depth.

This cannot be done in one step because the strokes must keep the internal layers order without using z-depth values.

Still some problems with z-depth texture.

Undo z-depth manipulation method

This method is not enough precise to get clean drawings, so we need to find an alternative solution.

Cleaun: Add clamp to keep zdepth in valid range

Cleanup and move constant to defines

Fix keep thicknees by object

This option must be by object, not by scene.

Cleanup some code too and rename to use better naming for variables.

Add mid range for zfight

WIP: adjust the shift factor with distance

Cleanup: Remove unused code

WIP: zfighting al most fixed.

Need a way to fix the problem of zdepth and precision
