From: "Mike Gorchak"
Subject: SDL updates for the QNX6
1. Updated the README.QNX
2. Updated libtool scripts, which are shipped with SDL for QNX6 support.
3. Added some code to support the new QNX 6.3.0, which is in beta now.
4. Added code to detect the hw features, which driver supports.
5. Added hw alpha blits code.
6. Fixed bug when application switches to fullscreen more the 2 times. (afte\
r that window becames always stay on top).
7. Updated a bit README for the tests.
8. Added information about acceleration show in the testalpha.c test.
9. Added small fixes to the testoverlay2.c test.
10. Added alpha and cc+alpha blits benchmarks to the testvidinfo.c test.
