This add two new function that allows us to transform or project an array of points instead of only transforming one point at a time. Recent benchmarking has shown cogl_matrix_transform_point to be a bottleneck sometimes, so this should allow us to reduce the overhead when transforming lots of vertices at the same time, and also reduce the cost of 3 component, non-projective transforms. For now they are marked as experimental (you have to define COGL_ENABLE_EXPERIMENTAL_API) because there is some concern that it introduces some inconsistent naming. cogl_matrix_transform_point would have to be renamed cogl_matrix_project_point to be consistent, but that would be an API break. |
