Make sure the thread is actually paused, and context backep-up, before SurfaceView is destroyed (eg surfaceDestroyed() actually returns). Add a timeout when surfaceDestroyed() is called, and check 'backup_done' variable. It prevents crashes like: #00 pc 000000000000c0d0 /system/lib64/libutils.so (android::RefBase::incStrong(void const*) const+8) rsn8887#1 pc 000000000000c7f4 /vendor/lib64/egl/eglSubDriverAndroid.so (EglAndroidWindowSurface::UpdateBufferList(ANativeWindowBuffer*)+284) rsn8887#2 pc 000000000000c390 /vendor/lib64/egl/eglSubDriverAndroid.so (EglAndroidWindowSurface::DequeueBuffer()+240) rsn8887#3 pc 000000000000bb10 /vendor/lib64/egl/eglSubDriverAndroid.so (EglAndroidWindowSurface::GetBuffer(EglSubResource*, EglMemoryDesc*)+64) rsn8887#4 pc 000000000032732c /vendor/lib64/egl/libGLESv2_adreno.so (EglWindowSurface::UpdateResource(EsxContext*)+116) rsn8887#5 pc 0000000000326dd0 /vendor/lib64/egl/libGLESv2_adreno.so (EglWindowSurface::GetResource(EsxContext*, EsxResource**, EsxResource**, int)+56) rsn8887#6 pc 00000000002ae484 /vendor/lib64/egl/libGLESv2_adreno.so (EsxContext::AcquireBackBuffer(int)+364) rsn8887#7 pc 0000000000249680 /vendor/lib64/egl/libGLESv2_adreno.so (EsxContext::Clear(unsigned int, unsigned int, unsigned int, EsxClearValues*)+1800) rsn8887#8 pc 00000000002cb52c /vendor/lib64/egl/libGLESv2_adreno.so (EsxGlApiParamValidate::GlClear(EsxDispatch*, unsigned int)+132)

…arently handle more of the work. 1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority. 2. Add a hint to override SDL's default behavior for scheduler policy. 3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority. 4. Add hint checks in SDL_SetThreadPriority so that rsn8887#3 can be overridden if desired. 5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API. 6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires. Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.

This makes values set by
SDL_SetTextureColorModandSDL_SetTextureAlphaModrender properly on a Vita. I'm no SDL master and I don't know how fast this is or whether it conforms to code standards. However, this change made my SDL game port render identically as on PC, both tinting and transparency effects, with no noticeable effect on performance.
