gl oit: fix several issues 

Disable blending when rendering a-buffers. Fixes ECW Anarchy Rulz black
title screen and Demolition Racer glitchy end of race screen.

Use palette in the depth pass for punch-through polygons using palette
texture. Fixes shadow issue in Alone in the Dark.

Copy ouput fbo to geom_fbo before drawing. Fixes missing transparent
polygons in subsequent partial renders. Fixes Test Drive Le Mans missing
labels in loading screen.

Issue #1262
