* Merged MIXER CROP, MIXER ANCHOR, MIXER ROTATION and MIXER PERSPECTIVE from 2.0

* Merged MIXER CROP, MIXER ANCHOR, MIXER ROTATION and MIXER PERSPECTIVE from 2.0
* Merged reporting of current MIXER values when no parameters are given.
* Changed so that each vertex / texture coordinate pair in frame_geometry is encapsulated in a struct, to not require producers to keep track of indexes in an a array.
* Changed so that the same code in image_kernel draws a single QUAD and a list of QUAD's
* TODO make perspective correction and cropping work with non default geometry like the text producer. Currently no cropping or perspective correction works for custom geometry.
* TODO make interaction coordinate translations work with new transforms.
* Reverted text_producer change so that the baseline of the font is the actual position.
* Fixed so that JSON encoded template data is also forwarded as is, instead of being interpreted as an .ftd file name.
* Implemented anchor, crop, perspective and rotation support in scene_producer
