Daniel Stone 55bcb93fef gl-renderer: Use helper for conversion to EGL rects ... eglSwapBuffersWithDamage has to convert a damage region from Weston's global co-ordinate space, into the co-ordinate space for EGL rendering into a buffer for that output. The conversion from the global co-ordinate space in logical pixels to the output space in buffer pixels is slightly long and error-prone, involving translating by the output's offset within the global co-ordinate space, multiplying by output scale, and also translating to allow for any borders we paint around the output. After this is done, we need to flip the co-ordinates in the Y axis to account for the lower-left-origin co-ordinate space used by EGL. Since we want to reuse this for partial_update, but using a different source region, extract this conversion into a well-commented helper we can reuse.
