Trails and Line Renderer Upgrade

[Lunat12]

Upgrade on Trail Component

• Bloom option was added (mark the bloom check to use.)
• Textures were added (drag a texture to the texture slot to use. You can swap textures but not remove them at present.)

Line Renderer Component Added

Line renderer allows creating a visual line joining two or more points. When adding this component, it will automatically have two points created. You can add, remove, and select points on the editor's left panel. Once a point is selected, the edition options will appear on the right panel.

Point Options

• Position: You can either enter each point's position coordinates manually or drag an object from the scene to copy its transform. Dragged transforms can be removed. Remove the transform from the point before deleting the object that is being mimicked from the scene; otherwise, right now it's not controlled and will crash.
• Width: Enter the width of the line at each point.

Other Options

• Color Gradient: Modify the gradient applied to the rendered line by adding marks at the bottom to adjust color and at the top to adjust opacity. (Limit the total number of marks to no more than 10.)
• Bloom: Mark the bloom check to use.
• Texture: Drag a texture to the texture slot to use. You can swap textures but not remove them at present.

The new options are very useful and they work as indented.
The only thing that is working a little bit strange is when I assign a texture. The bug affect the trails and the line renderer.
When I create a trail or a line render, and I add a texture to it, the next ones I create, if I not assign them a texture, instead of using the default trail or line, they use the texture assigned in the previous trail or line. I add a link to a youtube video where this can be seen.
If this bug is solved, for me the pr can be accepted. Good job.
