Change layer hue/brightness/saturation/opacity etc

Amazingly there's no apparent way to change layer hue! To change the colour of a layer (ie a copied layer) seems like we have to convert it all to an "image".

I see there's another request for change layer opacity, so I suggest combining all of these functions into one node, or set of nodes.

Simple Keystone Node

Hi I'd love it if there was a simple keystone node. The current "quad layer" node is clunky in my opinion. Firstly it changes the image to layer which strikes me as very odd.

Also there isn't any node to crop/mask shapes from the image (ie diagonal lines across the image).

So I'm proposing a simple node of the image class that can keystone the image... and while I'm here I'm proposing that it can be used to diagonally crop pieces of the image too.

Feel free to point it out if there is one already.

Gradient Phase and Period

Would it be possible to add phase and period controls to the gradient image generators to make repeating and animated patterns? For example, give a Make Linear Gradient Image 3 colours but then give it a small period to repeat the 3 colours over and over. Phase would then let you animate the gradient over time with options similar to the Change Wrap Mode node such as mirror, hold, repeat etc. It would also be great to have interpolation method control between the colours in order to make hard steps.

Deformable Mesh

A node that generates a 2D mesh that is able to be deformed with smooth curves. Useful for advanced projection mapping. Vuo is already able to do this using Paul Bourkes mesh deformation software, but a solution that allows custom control within Vuo of each point could be very useful for mapping onto irregular surfaces.

Otherwise possibly a way to generate mesh mapping values from within Vuo for the Mesh Mapping node.

As discussed on Node to generate Paul Bourke’s mesh data file (.data) format, this node would have the option to input either all grid points or just a subset of grid points. "The node assumes that if there is no values in the list- then it simple passes a perfect grid of values. If there are values in the list it uses them to deform the grid in the manner that is indicated."
