When logging a quad we now only store the 2 vertices representing the top left and bottom right of the quad. The color is only stored once per entry. Once we come to upload the data we expand the 2 vertices into four and copy the color to each vertex. We do this by mapping the buffer and directly expanding into it. We have to copy the data before we can render it anyway so it doesn't make much sense to expand the vertices before uploading and this way should save some space in the size of the journal. It also makes it slightly easier if we later want to do pre-processing on the journal entries before uploading such as doing software clipping. The modelview matrix is now always copied to the journal entry whereas before it would only be copied if we aren't doing software transform. The journal entry struct always has the space for the modelview matrix so hopefully it's only a small cost to copy the matrix. The transform for the four entries is now done using cogl_matrix_transform_points which may be slightly faster than transforming them each individually with a call to cogl_matrix_transfom. |
