Avoids an explicit use of sizeof(). The GLib allocation macros ensure that the multiplication by the size of the element uses the right type and does not overflow. While at it, change bitmap_new() to use g_new0 directly. Its current impl of calling bitmap_try_new() followed by a plain abort() has worse diagnostics than g_new0, which uses g_error to report the actual allocation size that failed.
