Subject: [PATCH] [truetype] Reload context after re-executing `prep`.

When a different hinting mode from the current is selected, the `prep` table
must be re-executed with the new mode.  After this happens the context must
be re-loaded in preparation for the glyph program to be run.

Fixes #1104.

* truetype/ttgload.c (tt_loader_init): Add call to `TT_Load_Context`.
