From: "Mike Gorchak"
Subject: New QNX patches

In photon.tar.gz there are new files to be placed into ./src/video/photon/
directory.

qnx3.diff - new patches for QNX support. Since I've found a lot of bugs in
the new GF QNX Graphics Framework and I'm suspended development for GF
driver until already found bugs will be fixed and switched to Photon driver
implementation.

sdl.diff - I've found that renderer creation result has not been checked and
SDL shows error like: "there is no current renderer", now SDL will show
correct error which was set be renderer.

 QNX Photon and GF drivers are under construction. Please be patient.

+ -- SDL GF driver --
+---------------------
+
+Here is an additional information about SDL GF driver:

+ * 1. Environment variables which SDL GF driver supports.
+ * 2. Custom video modes.
+ * 3. Limitations.
+
+0. Introduction.
+
+   SDL GF driver is a layer between SDL and QNX Graphics Framework (GF). Hardware
+accelerated features which SDL could support depends on real hardware capabilities.
+
+1. Environment variables which GF driver supports.
+
+   GF driver supports the following environment variables for QNX GF specific
+customization options:
+   a) SDL_VIDEO_GF_REFRESH_RATE - refresh rate of video output in Hz. Without
+      this environment variable declaration SDL controls refresh rate of your
+      display. If this enironment variable is set to 0, SDL will control refresh
+      rate of display, otherwise value of SDL_VIDEO_GF_REFRESH_RATE is used for
+      all screen resolutions as refresh rate. This example will set 60Hz refresh
+      rate as refresh rate for all graphics modes:
+
+      export SDL_VIDEO_GF_REFRESH_RATE=60
+
+2. Custom video modes.
+
+   Since most QNX graphics drivers supports GENERIC video modes, i.e. you could
+specify any horizontal and vertical resolution and any refresh rate, SDL GF
+driver uses its own fullscreen modes list, which could be incomplete. You could
+add any custom video mode, which your QNX graphics driver supports by editing
+file ./src/video/qnxgf/SDL_qnxgf.c. Custom graphics mode definition looks like
+
+   {0, 1024, 640, 60, NULL},   /* 1024x640 mode is 60Hz only               */
+
+You must specify horizontal resolution as second parameter, vertical resolution
+as third parameter and refresh rate as fourth parameter. Please leave first and
+last parameters as 0 and NULL. Then please send me your changes to e-mail address
+which is specified in the header of this document.
+
+3. Limitations.
+
+   There are few limitations while using SDL GF driver:
+
+   a) Since GF driver supports fullscreen modes only, when you are not specifing
+SDL_WINDOW_FULLSCREEN flag, an SDL GF driver will try to find the fullscreen
+graphics mode which corresponds to SDL window size. Refresh rate will be the
+lowest available, if SDL_VIDEO_GF_REFRESH_RATE environment variable is not set.
