Introduction to Glitz
Glitz is an OpenGL image compositing library. Glitz provides Porter/Duff compositing of images and implicit mask generation for geometric primitives including trapezoids, triangles, and rectangles.
The semantics of Glitz are designed to precisely match the specification of the X Render extension. Glitz not only implements X Render features like component alpha and image transformations, but it also implement support for additional features like convolution filters and color gradients, which are not currently part of the X Render specification.
The performance and capabilities of Glitz are very dependent on your graphics hardware. Glitz does not in any way handle software fall-backs when the graphics hardware is insufficient. However, Glitz will report if any requested operation cannot be carried out by the graphics hardware, thus making a higher level software layer responsible for appropriate actions.
Glitz can be used as a stand-alone layer above OpenGL but is also designed to act as a backend for Cairo, providing it with OpenGL accelerated output.
