Fixed bug 3304 - Android black screen on resume

Browse Source 
Richard Russell

Resuming from a suspended state results in a black screen.  This only happens when using GLES 1.1 (GLES 2 resumes correctly) and when the render target has been changed using SDL_SetRenderTarget.  This problem is new in 2.0.4.

The attached test case demonstrates the issue.

Sylvain Becker has apparently found a fix as follows:

"In the opengles leaf function (in 'src/render/opengles/SDL_render_gles.c'), it appears there is a call to 'GLES_ActivateRenderer' in 'GLES_SetRenderTarget', which is not present in opengles2. When commenting out this 'GLES_ActivateRenderer', it seems to resume fine".

This appears to fix the testcase perfectly, but I don't know whether it could have any undesirable side-effects.
