Subject: About QNX support in SDL 1.3
Right now I'm working on QNX SDL 1.3 drivers implementation and looks like a
lot of code must be completely reworked. But I'm ready for it :) Also I want
to add QNX Graphics Framework SDL driver, which is fullscreen graphics
framework, with support of hardware accelerated OpenGL ES implementations.
This Graphics Framework (called GF in QNX) could also use QNX Photon (window
manager GUI) as window manager.
In the attachment initial patch for QNX support in SDL 1.3
