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.

Photon emits keyboard events (key up and down) when the mouse
wheel is moved. The key_scan field appears valid, and it contains zero.
That is a basic method of detecting mouse wheel events under Photon.

It looks like a hack, but it works for me :) on various PC configura-

I've tested it on:

1. Genius Optical NetScroll/+ (1 wheel)
2. A4Tech Optical GreatEye WheelMouse, model: WOP-35. (2 wheels + 2
additional buttons). The wheel for vertical scrolling works as usu-
al, but the second wheel for horizontal scrolling emits two sequen-
tial events up or down, so it can provide faster scrolling than the
first wheel. Additional buttons don't emit any events, but it looks
like they're handled by photon in an unusual way - like click to
front, but works not with any window, looks like bug-o-feature :).
