BuGLe is an open source tool for OpenGL API code debugging, implemented as a wrapper library that sits between your program and OpenGL. It allows a developer to view OpenGL state at any time. The new release adds initial support for OpenGL 2.1 (e.g. non-square uniform matrices, GL_CURRENT_RASTER_SECONDARY_COLOR) and supports depth and luminance textures, and display of RGBA and UV values in texture viewer.
