From 77d4db015c99ce7083fd5b33f0c650176fe8bc98 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 25 May 2009 18:20:05 -0300 Subject: Fix vga_screen_dump_blank() PPM generation vga_screen_dump_blank() was not generating a valid PPM file: the width of the image made no sense (why it was multiplied by sizeof(uint32_t)?), and there was only one sample per pixel, instead of three.
