 /**
+ * Same as util_blitter_copy_texture, but dst and src are pipe_surface and
+ * pipe_sampler_view, respectively. The mipmap level and dstz are part of
+ * the views.
+ *
+ * Drivers can use this to change resource properties (like format, width,
+ * height) by changing how the views interpret them, instead of changing
+ * pipe_resource directly. This is usually needed to accelerate copying of
+ * compressed formats.
+ *
+ * src_width0 and src_height0 are sampler_view-private properties that
+ * override pipe_resource. The blitter uses them for computation of texture
+ * coordinates. The dst dimensions are supplied through pipe_surface::width
+ * and height.
+ *
+ * NOTE: There are no checks whether the blit is actually supported.
