The _cogl_propagate_error() function takes ownership of the incoming<br>
<div class="im">error pointer so there's no need to allocate a new error when passing<br>
it on. The errors can potentially be passed up from a number of layers<br>
so it seems worthwhile to avoid the allocation.<br>
<br>
</div>The _cogl_propagate_gerror() function was previously using<br>
_cogl_propagate_error(). Presumably this would not have worked because<br>
that function would try to free the error from glib using<br>
cogl_error_free but that would use the wrong free function and thus<br>
the wrong slice allocator. The GError propagating function is only<br>
used when gdk-pixbuf is enabled which now requires glib support anyway<br>
so we can just avoid defining the function when compiling without<br>
glib.<br>
