Yune-v4.0

This is the first release that is decent enough to be used by others. Removed NanoGUI, FreeImage and Eigen as dependencies and instead added DearImGui, Glm and stb_image_write.

Overhauled the GUI and added a bunch of options to be configured by the programmer such as setting the camera matrix, setting kernel workgroup sizes etc.

Yune-v3.0

Fixed a couple of existing bugs in UDPT. Naive bdpt implemented. Model loading support (althought currently it reads custom obj files, need to fix in future release)

Yune-v2.0.1

Bug fixes

• Place proper Acquire and Release GL objects commands before enqueuing post-processing kernel. This caused black screen on certain platforms not supporting cl_khr_gl_event

• Update FPS code so FPS no longer shoots up after you stop moving the camera.

Yune-v2.0

Added Features,

-Multiple Importance Sampling
