TODO

• GL backend: textures --- try make the d3d11 backend support multiple textures first and

           then generalize to gl
  
           for d3d11: we need to reflect bound resources for both vs and ps... if they are
           shared then perhaps we only need one buffer -- also, should you create less buffers
           and reuse them between shaders? So it doesn't become lots of buffers for each shader
           permutation
  

  X set uniforms -- needs more type info? X the constant types are hardcoded to just a few types right now

• should gamepad come from separate interface than window?

  • keyboard input could also come from some input interface, but it is tightly bound to window in windows, so we'll see.

• add more window flags

• win32: Gamepad support

  • check status of gamepad
  • what happens when you pull one out?
  • playstation

• Textures: Make the sampler state configurable

• Textures D3D11: Do we need the SRV in the texture?

• Shaders: Reflect and expose samplers

  • generalised sampler handling for both gl and d3d

• mipmap support

• set filtering: for scaling up, down and mipmap

• render textures

• do pixel-perfect rendering tests: render texture with 1:1 pixel matching etc

• linux windowing and input

• webgl backend

• should we expose time and delta time stuff or rely on core:time?

• think about sound

DONE

• Should we sort by depth? Maybe we should use Vec3 because some 2D games rely on it?
  • I think we should.
• Do proper checks of vertex count and dispatch rendering when full
  • What happens when list is full? We can't just empty the vertex list due to being used by input assembler etc.
• basic text rendering (ended up using font stash)
  • make draw_text and load_default_font do somethig more sensible
  • look at how to properly get the scale from stb_ttf
  • compare if we are doing the same as raylib by loading its default font and drawing some things, can we make it look similar?
  • font smoothing -> make it look crisp by disabling filtering on "pixel fonts"
  • next stage: Look into something more fancy than just loading bitmaps. What can we do?
• bunnymark
• win32: Resizable window
• Flashing textures in Abyss -- Better now but still flashes when you use nose... Check the "odd_frame" stuff in d3d backend
• Is the 1/zoom in set_camera wrong? Is the matrix multiply order wrong? Hmmmm...
• Fix the depedency on D3D stuff so we can move load_shader etc
• Shaders: Basic loading
• Shaders: Constants that you can set
• Shaders: Dynamic vertex creation
• Shaders: Feed extra vertex field values using some kind of context
  • Do we need one for all corners of a rect or possibilty to supply different value for the different corners?
• Group set_tex, camera etc into a section of things that cause a render batch dispatch when changed.
• Make a texture for drawing a rectangle and remove the hack in shader.hlsl
• Load textures and somehow bind to shader -- split draw calls on texture switch -- needs a start of a batch system.
• Make 0, 0 be at top left (should vertex data be flipped, or is it a transformation thingy?)
• Construct vertex buffer from k2.draw_blabla calls. Do we need index buffer? 🤷‍
• Organize the d3d11 things neatly. It's just a hack right now!
  • enable debug layers
  • asserting on hresult and checking errors
  • clean up on shutdown
