This is an attempt at resurrecting Daniel's MR [1] which was already resurrecting Harish's EGL_KHR_partial_update series [2]. This version implements Marek's suggestion to pass the set_damage_region() directly to the gallium driver and let it decide how to handle the request. Some drivers might just calculate the damage extent (as done in Daniel's initial proposal and in the panfrost implementation), others might do extra optimizations like trying to reduce the area we're supposed to reload (only valid for tile-based rendering) even further.
This patch series has been tested with weston on panfrost. Note that the panfrost implementation is rather simple (just limits the rendering area to the damage extent and picks the biggest damage rect as the only damage region) but we can improve it if we feel the need. No major changes in this v7, just added the missing FREE(boxes) call in dri2_set_damage_region() and fixed an alignment issue in the panfrost driver.
