=================================================================
Patch version 0.8 of SDL(Simple DirectMedia Layer) for Nano-X API
=================================================================
Author: Hsieh-Fu Tsai, clare@setabox.com
There are two patch files in this package.
1. The first patch file, nanox.patch, is to fix a bug in Nano-X.
This patch is proposed by Gary James (gjames@twcny.rr.com).
It fixes the client side GrClose(). In the original version,
GrOpen() can only be called once. When the GrOpen() is called at
the second time, the program will terminate. In order to prevent
this situation, we need to insert "nxSocket = -1" after
"close(nxSocket)" in GrClose(). If you do not have this problem,
you may skip this step.
=============
Quick Install
=============
1. ./configure --disable-video-x11 --disable-video-fbcon \
--enable-video-nanox \
--with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal]
2. make clean
3. make
4. make install (as root)
============
Nitty-gritty
============
--with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal]
If the wrong pixel type is used, the program will crash when the
sub-routine updates the screen. This option depends on SCREEN_PIXTYPE
which is defined in Microwin0.89pre7/src/config. SCREEN_PIXTYPE
is used to define the pixel type in Microwindows/Nano-X.
I only test the program when the pixel type is in "rgb"
(Microwin under X11) or "888" (framebuffer in 24-bit).
--enable-nanox-debug Show debug messages
--enable-nanox-share-memory Use shared-memory to speed up
=============================================
Some programs can be used to test this patch.

Todo List
=========
1. Create hardware surface
2. Create YUVOverlay on hardware
3. Use OpenGL
4. Gamma correction
5. Hide/Change mouse pointer
