From ee72bed08cc05f086ad1424e47f1b06461650381 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 5 Apr 2017 09:02:47 +0100 Subject: tcx: remove primitives for non-32-bit surfaces As all surfaces in QEMU are now either shared or 32-bit ARGB regardless of the guest depth, remove all non-32-bit primitives from tcx_update_display() and consequence their implementation which are no longer required.
