[Cogl] [PATCH] blit: avoid using _COGL_GET_CONTEXT

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

As part of an on-going effort to avoid depending on a global Cogl
context cogl-blit.c now finds the context by looking at
data->src_text->context instead of using the _COGL_GET_CONTEXT macro.
