Yea, I didn't see a good way of doing it as well.
Most likely the best approach would be to have static entry points for
individual apis. e.g. vg_create_context, es11_create_context,
es20_create_context or such (resolved at runtime),each that take a struct with
function pointers that can be filled with the respective interfaces.
E.g.
struct egl_context_api {
void *state_tracker;
void * (*create_framebuffer)(const void *visual,
enum pipe_format colorFormat,
enum pipe_format depthFormat,
enum pipe_format stencilFormat,
uint width, uint height,
void *privateData);
void (*make_current)(struct egl_context_api *st,
struct st_framebuffer *draw,
struct st_framebuffer *read);
...
};
that the state trackers can fill.
