[PATCH 0/1] MR761: tests/shader_runner: Report compilation errors on the block's starting line.

[Francisco Casas (＠fcasas)]

I think this has proven to be problematic a couple of times already.

With this patch, if there is an error or a trace on `[pixel shader]` or similar
blocks, they get reported in the line with the tag at the beginning of
the block and no on the line where the next block starts.
