[Mesa-dev] [PATCH 2/2] i965: Fix depth (array slices) computation for 1D_ARRAY render targets.

[Kenneth Graunke]

1D array targets store the number of slices in the Height field.

Fixes Piglit's spec/!OpenGL 3.2/layered-rendering/clear-color-all-types
1d_array single_level, at least when used with Meta clears.
