Textures, FrameBuffers and VertexBuffers allocated by the Sdl2 Renderer were only being released via finalizers. This could lead to OpenGL out of memory errors since resources may not be cleaned up in a timely manner. To avoid this, IDisposable has been implemented and transitively applied to classes that use these resources.
As a side-effect some static state is no longer static, particularly in Renderer, in order to facilitate this change and just for nicer design in general.
Also dispose some bitmaps.
- Create single platform config named x86 and have all projects target x86.
- Remove Release config (broken anyway).
- For the Debug config, ensure TRACE and DEBUG constants are set and unsafe code is allowed for all projects (same as the makefile).
- Warn level 4 and optimizations off were removed from the config automatically by VS (it assumes these values by default, and these match the makefile).
- The CrashDialog project can reuse the icon from the Game project as long as the path is set correctly.
- Fix TS project so it builds (I know it's going but its annoying that the project must be unloaded).
- Implement IDisposable interface correctly, with sealed classes where possible for simplicity.
- Add using statement around undisposed local variables.
- Made private methods static where possible (runtime can elide checking the object for null).
- Declared attribute classes as sealed (allows reflection on attributes to complete faster).
- Moved some static cctor's into field initializers (static cctor's are slower than static field initializers).
- Made classes static if they contained only static methods (can't create instances of useless objects).
- Use inferable Exts.Lazy and not new Lazy<T>().
- Added required STAThread attribute to CrashDialog.
- Removed unused parameters in private methods.
- Added Serializable attribute to exceptions.
- Added parameter name in calls to ArgumentNullException.
- Use of as operator instead of is + cast.
- Changed (x as Foo).Bar anti-pattern into ((Foo)x).Bar. Results in sensible cast exceptions on error rather than null dereferences.
- Removed unused method in NullShader.
Create a single solution platform named x86.
Ensure both Debug and Release configs build to the root for all projects.
Ensure all Release configs generate pdbs.
* The GL texture id is now readonly.
* Added Size property.
* Added GetData() for reading data back from the GPU.
* Added SetEmpty() for creating an empty texture of a given size.
