ef21ccf080 Create a separate metal shader for NV12 textures
Also unify the color output function so it works with the various combinations of input and output colorspaces.

54c2ba6afd Added the Chrome HDR tonemap operator
Also added support for the SDL_PIXELFORMAT_XBGR2101010 pixel format to the D3D12, D3D11, and Metal renderers.

7fa5e95b62 Fixed bug 5213 - Add support to metal in iOS/tvOS simulator
Vincent Hamm

Xcode11 and ios13 added support for metal simulator.
Here is a quick and dirty patch to enable it. Pretty early and only tested on a few samples for now. Required mostly to enable metal support on correct version of ios, generate simulator compatible shaders and enforce buffer alignments on simulator (same as osx).

e8278d0d5b metal renderer: use vertex attributes instead of indexing into a buffer with the vertex id in the shader. Allows for more flexibility with vertex setup in the future.
Also optimize vertex buffer binding slightly.

e5acccc7c3 metal renderer: use the device address space instead of the constant address space for colors.
It doesn't negatively impact GPU performance in my tests, and it removes the need for 256 byte memory alignment of color data on macOS.

888198ee31 metal: Misc. improvements.
- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.

639ea9fdbc metal: Use sampler state objects instead of shader-declared samplers for linear vs nearest filtering.
This avoids a ton of shader duplication once multiple shaders that use samplers are added (e.g. the currently missing YUV shaders).
