* Add batched drawing API
Internally Clyde batches drawing, however when drawing hundreds / thousands of the same quad the batch checks add up. This just omits those checks and directly draws instead. Same with skipping color modulation.
Long-term could probably figure out a way to SIMD the transforms better.
* RN
* Add load parameter support to RSIs.
Currently only supports turning sRGB off. RSIs with custom load parameters are not thrown into the meta-atlas.
As part of this, TextureLoadParameters and TextureSampleParameters has been made to support equality.
* Add UV2 channel to vertices.
This is a bad hack to make displacement maps work in Robust. The UV2 channel goes from 0 -> 1 across the draw and can therefore be used by displacement maps to map a separate displacement map layer on top of the regular meta-atlas RSI texture.
This creates float inaccuracy issues but they weren't bad enough to completely void the feature. I'm thinking I learn from this experience and completely re-do how UVs work with the renderer rewrite, so that hopefully won't happen anymore.
This required dumping the optimized PadVerticesV2 because the changed struct size made it impractical. RIP.
I don't like this approach at all but the renderer is slated for a rewrite anyways, and all shaders will need to be rewritten regardless.
* Add CopyToShaderParameters for sprite layers.
This effectively allows copying the parameters of a sprite layer into another layer's shader parameters. The use case is to copy texture coordinates for displacement maps, as the exact map used changes depending on orientation. It also enables animations to be used though I didn't use that personally.
* Added documentation to Clyde on the sprite rendering calls.
* Added a rotation debug entity.
* Non-directional RSIs and raw textures are now rotated properly.
* Directional RSIs and Sprite Smoothing work.
* Remove the Directional flag usages.
* Supports layers with different numbers of directions.
* Fixes window rendering.
* Removed the Interfaces folder.
* All objects inside the GameObjects subfolders are now in the GameObjects namespace.
* Added a Resharper DotSettings file to mark the GameObjects subfolders as not providing namespaces.
* Simplified Robust.client.Graphics namespace.
* Automated remove redundant using statements.
* Adds a derived class from Nunit's Is test constraint class.
The game camera can now be rotated.
* Added the new `bind` command to the console, used to bind a key to a keybind.
Added two new keybinds for rotating the View camera left and right.
Added more info to the ""Component does not exist for state" exception.
Added Reduced() and FlipPositive() public functions to Angle.
* Fix a copy/paste bug.
* Adds missing code to bind/unbind CameraRotateLeft.
Camera snapping now actually uses the CameraSnapTolerance constant.
* Refactor UI system.
Deferred updating is used for styling & layout. This fixes the awful time complexity of containers.
Removed SetDefaults and Initialize. They were a bad idea alright.
* Fix build on .NET Framework.
* Attempted Clyde cleanup, didn't get far.
* Add negation operator to Vector2i.
* Add RenderOrder to ISpriteComponent.
* Post process shaders.
Adds "post process" shaders to sprite component.
These are executed on the WHOLE sprite component (every layer)
in one draw.
This is necessary to implement functional outlines.
