Add 2d meshes and materials (#3460) # Objective The current 2d rendering is specialized to render sprites, we need a generic way to render 2d items, using meshes and materials like we have for 3d. ## Solution I cloned a good part of `bevy_pbr` into `bevy_sprite/src/mesh2d`, removed lighting and pbr itself, adapted it to 2d rendering, added a `ColorMaterial`, and modified the sprite rendering to break batches around 2d meshes. ~~The PR is a bit crude; I tried to change as little as I could in both the parts copied from 3d and the current sprite rendering to make reviewing easier. In the future, I expect we could make the sprite rendering a normal 2d material, cleanly integrated with the rest.~~ _edit: see <https://github.com/bevyengine/bevy/pull/3460#issuecomment-1003605194>_ ## Remaining work - ~~don't require mesh normals~~ _out of scope_ - ~~add an example~~ _done_ - support 2d meshes & materials in the UI? - bikeshed names (I didn't think hard about naming, please check if it's fine) ## Remaining questions - ~~should we add a depth buffer to 2d now that there are 2d meshes?~~ _let's revisit that when we have an opaque render phase_ - ~~should we add MSAA support to the sprites, or remove it from the 2d meshes?~~ _I added MSAA to sprites since it's really needed for 2d meshes_ - ~~how to customize vertex attributes?~~ _#3120_ Co-authored-by: Carter Anderson <mcanders1@gmail.com> 2022-01-08 01:29:08 +00:00			`mod color_material;`
