profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

Re-design the matrix stack using a graph of ops This re-designs the matrix stack so we now keep track of each separate operation such as rotating, scaling, translating and multiplying as immutable, ref-counted nodes in a graph. Being a "graph" here means that different transformations composed of a sequence of linked operation nodes may share nodes. The first node in a matrix-stack is always a LOAD_IDENTITY operation. As an example consider if an application where to draw three rectangles A, B and C something like this: cogl_framebuffer_scale (fb, 2, 2, 2); cogl_framebuffer_push_matrix(fb); cogl_framebuffer_translate (fb, 10, 0, 0); cogl_framebuffer_push_matrix(fb); cogl_framebuffer_rotate (fb, 45, 0, 0, 1); cogl_framebuffer_draw_rectangle (...); /* A */ cogl_framebuffer_pop_matrix(fb); cogl_framebuffer_draw_rectangle (...); /* B */ cogl_framebuffer_pop_matrix(fb); cogl_framebuffer_push_matrix(fb); cogl_framebuffer_set_modelview_matrix (fb, &mv); cogl_framebuffer_draw_rectangle (...); /* C */ cogl_framebuffer_pop_matrix(fb); That would result in a graph of nodes like this: LOAD_IDENTITY | SCALE / \ SAVE LOAD | | TRANSLATE RECTANGLE(C) | \ SAVE RECTANGLE(B) | ROTATE | RECTANGLE(A) Each push adds a SAVE operation which serves as a marker to rewind too when a corresponding pop is issued and also each SAVE node may also store a cached matrix representing the composition of all its ancestor nodes. This means if we repeatedly need to resolve a real CoglMatrix for a given node then we don't need to repeat the composition. Some advantages of this design are: - A single pointer to any node in the graph can now represent a complete, immutable transformation that can be logged for example into a journal. Previously we were storing a full CoglMatrix in each journal entry which is 16 floats for the matrix itself as well as space for flags and another 16 floats for possibly storing a cache of the inverse. This means that we significantly reduce the size of the journal when drawing lots of primitives and we also avoid copying over 128 bytes per entry. - It becomes much cheaper to check for equality. In cases where some (unlikely) false negatives are allowed simply comparing the pointers of two matrix stack graph entries is enough. Previously we would use memcmp() to compare matrices. - It becomes easier to do comparisons of transformations. By looking for the common ancestry between nodes we can determine the operations that differentiate the transforms and use those to gain a high level understanding of the differences. For example we use this in the journal to be able to efficiently determine when two rectangle transforms only differ by some translation so that we can perform software clipping.
