KNOWN ISSUES
--------------------------------------------------------------------------------
1. At this stage only shader-based (OpenGL ES 3.0) pipeline works. The fixed
pipeline (GLES 2.0) could work (it works under linux), but it doesn't look
good and is generally broken. It means that it's not possible to run STK on
Android 4.2 or older. It is technically possible to do - check GLES context
version, load OpenGL functions dynamically using EGL, and if they are not
loaded properly, then fallback to GLES 2.0. But these devices may be too
slow to run STK anyway.
1. It's not possible to compile STK for Android < 4.4 due to missing GLES 3.0
functions. It is technically possible to do - check GLES context version,
load OpenGL functions dynamically using EGL, and if they are not loaded
properly, then fallback to GLES 2.0.
2. It never ocurred for me, but it's possible that EGL context is lost in some
cases. SuperTuxKart is not designed to re-create all textures at any moment,
so this is a "Wontfix", at least for now.
3. Some bright tracks (Farm, Gran Paradiso) seem to be a bit darker in GLES
renderer than in original OpenGL 3.x renderer. It can be easily hacked by
adding few lines to object pass shader, but we should rather try to find the
real reason.
4. We use "exit(0)" at the end of main function. We shouldn't do it and we
3. We use "exit(0)" at the end of main function. We shouldn't do it and we
should just return from the main function. But STK uses some global
variables and their values are remembered when the game is restarted. We
should properly clear them or re-initialize on startup. Using the "exit(0)"

for this reason using NDK r12 for 64-bit arm compilation is preferred.
