The source allows you to apply effects to the same source without requiring a new instance of the source. Any changes done to the original source also apply to the mirror, so there is less total work that needs to be done.
It can also rescale the source, allowing you to use the same source as a cheap instant backdrop with Blur for example. What you do in the end is completely unwritten and up to you to decide.
This option allows applying the blur to other color formats such as YUV. Bilateral Blur benefits the most from this, resulting in smoother images at lower kernel sizes.
* Added a 'Bilateral' de-noising blur, currently very resource hungry. It also has two extra sliders called 'Smoothing' and 'Sharpness', the former controls how smooth the output is
* Updated effect loading to be global instead of per instance.
* Changed default blur size to 5px.
* Simplified render loop (see previous effect commit).
This is not very optimized at the moment and will take quite a bit of GPU time. Will have to spend some time later to optimize it and perhaps add directional blur ("Motion Blur" to it).
* Fixed the perspective mesh not filling the entire frame with the default settings.
* Changed the maximum range of 'Field of View' to 179 degrees instead of 180 degrees.
* Changed the direction the perspective camera looks at to +Z instead of -Z. This should feel more natural for users of other 3D programs.
* Changed the 'Position (Z)' default to 0.
* Added translation strings for 'Field Of View', 'Position', 'Scale' and 'Rotation'.
