| // debug interface: |
| // Since none of the "gl" methods are member functions they don't get |
| // a "this" pointer through which to access "fWrapped" |
| // This could be worked around by having all of them access the |
| // "glInterface" pointer - i.e., treating the debug interface as a |
| // true singleton |
| // |
| // The problem with this is that we also want to handle OpenGL |
| // contexts. The natural way to do this is to have multiple debug |
| // interfaces. Each of which represents a separate context. The |
| // static ID count would still uniquify IDs across all of them. |
| // The problem then is that we couldn't treat the debug GL |
| // interface as a singleton (since there would be one for each |
| // context). |
| // |
| // The solution to this is probably to alter SkDebugGlContext's |
| // "makeCurrent" method to make a call like "makeCurrent(this)" to |
| // the debug GL interface (assuming that the application will create |
| // multiple SkGLContextHelper's) to let it switch between the active |
| // context. Everything in the GrDebugGL object would then need to be |
| // moved to a GrContextObj and the GrDebugGL object would just switch |
| // between them. Note that this approach would also require that |
| // SkDebugGLContext wrap an arbitrary other context |
| // and then pass the wrapped interface to the debug GL interface. |
