- Removed explicit PCH.
- Fixed includes to compile for all supported engine versions, including non-unity builds.
- Configured build.cs to treat ImGui as an engine module and added stricter compilation rules.
- The old DPI Scale setting was replaced by DPI Scaling Info, which contains information about scale and method of scaling.
- ImGui Context Manager handles scaling in ImGui by scaling all styles, rebuilding fonts using a different size, and raising OnFontAtlasBuilt event.
- ImGui Module Manager uses OnFontAtlasBuilt event to rebuild font textures.
- The update policy in Texture Manager was loosened to update existing resources rather than throwing an exception. This is less strict but it is now more useful since our main texture can now change. The throwing behavior used in the public interface is now handled before calling to the Texture Manager.
- Added ImGuiTextureHandle that is implicitly convertible to ImTextureID and can be used directly with ImGui interface.
- Added to ImGui Module interface allowing to register, update and release textures or find handles to existing resources.
- Refactored Texture Manager and added functions allowing create, update or release resources for user textures.
- Loosened resource verification policy in Texture Manager to work smoothly with external requests and to handle gracefully situations when invalid texture id is passed to ImGui.
- Introduced ‘error texture’ that is used for invalid resources.
- Fixed rather embarrassing overlook in deallocation of data array passed from to CreateTexture from other function.
- Changed CreateTexture to use cleanup function passed with data (optional and only needed if data need to be released). Keeping data allocation and deallocation code together should make bugs like this easier to spot and avoid. Additionally this allows for more generic usage.
- Added ImGui Module Manager that that implements module logic and manages other module resources.
- Added Texture Manager to manage texture resources and maps them to index that can be passed to ImGui context.
- Added Context Proxy that represents and manages a single ImGui context.
- Added Slate ImGui Widget to render ImGui output.
