/* TODO:
*
- * stride:
- *
- * The driver and the loaders (libGL, xserver/glx) compute the stride from the
- * width independently. winsys has a workaround that works for softpipe but may
- * explode for other drivers or platforms, rendering- or performance-wise.
- * Solving this issue properly requires extending the DRISW loader extension,
- * in order to make the stride available to the putImage callback.
- *
- * drisw_api:
- *
- * Define drisw_api similarly to dri1_api and use it to call the loader. This
- * is predicated on support for calling the loader from the winsys, which has
- * to grow for DRI2 as well.
- *
* xshm / texture_from_pixmap / EGLImage:
*
* Allow the loaders to use the XSHM extension. It probably requires callbacks
- * for createImage/destroyImage similar to DRI2 getBuffers. Probably not worth
- * it, given the scope of DRISW, unless it falls naturally from properly
- * solving the other issues.
- *
- * fences:
- *
- * No fences are used, are they needed for llvmpipe / cell ?
+ * for createImage/destroyImage similar to DRI2 getBuffers.
