Currently features are represented as bits in a 32bit mask so we obviously can't have more than 32 features with that approach. The new approach is to use the COGL_FLAGS_ macros which lets us handle bitmasks without a size limit and we change the public api to accept individual feature enums instead of a mask. This way there is no limit on the number of features we can add to Cogl. Instead of using cogl_features_available() there is a new cogl_has_feature() function and for checking multiple features there is cogl_has_features() which takes a zero terminated vararg list of features. In addition to being able to check for individual features this also adds a way to query all the features currently available via cogl_foreach_feature() which will call a callback for each feature. Since the new functions take an explicit context pointer there is also no longer any ambiguity over when users can first start to query features. Reviewed-by: Neil Roberts <neil@linux.intel.com> |
