Type definition used to specify a render request.
- FxPlug 3.1+
The pixel aspect ratio is not taken into account when the
scale values are computed. Plug-ins should look at the input and output
Fx structure to determine pixel aspect ratios.
shared allows the plug-in to create its own OpenGL context that shares the textures supplied by the application with the plug-in. You do not normally need to use this context unless you have to create a new context and share the input and output textures. Do not use this context directly for drawing, either. The application sets the current context to draw into the output texture before calling the plug-in.
