From 54b2a4339ccae45d4264c2437978abd04ff82bca Mon Sep 17 00:00:00 2001 From: Sebastian Bauer Date: Wed, 4 Jul 2018 11:40:58 +0200 Subject: [PATCH] sm501: Use values from the pitch register for 2D operations Before, crt_h_total was used for src_width and dst_width. This is a property of the current display setting and not relevant for the 2D operation that also can be done off-screen. The pitch register's purpose is to describe line pitch relevant of the 2D operation.
