Using ImGui to draw cursor helps to reduce visual error between mouse cursor and position in ImGui. But it has been reported that this works really bad when frame-rate drops and becomes unusable below ~20 FPS. Taking that into account hardware cursor seems like a better default option. Old behaviour can be enabled with ImGui.DrawMouseCursor console variable.
- Added ImGui Input State to collect and store input updates.
- Changed Slate ImGui Widget to handle Slate input events and store them in input state.
- Changed ImGui Context Proxy to copy input state to its context.
- 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.
