-Engine todo list:
+DONE:
-- Engine testing + game testing framework is a mess.
+- Implement idle orbit thing using the rotation in the level editor camera. (Cool transition effect?)
-- A lot of the graphics pipeline stuff is really bloated and repeats itself.
+- Level editor camera movement complete.
-- Sokol should be fully under a platform abstraction layer but it's not,
-  currently it's fine but it would be really nice to be able to have a metal, vulkan
-  webgpu backends at some point for the longevity of the engine. 
-- Backend sokol has a global named camera taking up the name which is fucking crazy.
 
+TODO:
+- Level format (just a hash map?). Store a matrix so that we can rotate and maybe scale blocks. Scaling will cause problems with RDM, so figure that out.
+- Trile color textures.
+- Sun lighting and shadowmap for levels.
+- A ground plane with customizable material (ground or water or maybe a reflective floor. Think about what part of this should be done with triles and what with textures.)
+- Sky editor and passing to shader.
+- Level saving
+- Trile atlas saving? JSON?
+
+PLANNED:
+- Render distance, sky and fog?
+- Load RDMs. Load into the Trile_GFX structure?
+- Render RDMs.
+- Start working on game port for proof of concept.
+- Maybe port tacoma in as a part of the engine in plain Vulkan without nvpro. Would also allow for cool ability to render levels as path traced for screenshots and references.
+- Improve the bz4x format, or figure out a pre-existing format.
