Description Pallav Nawani 2013-05-14 08:23:56 UTC 
The GL ES1 extension GL_OES_draw_texture does not play well with renderer scaling as done by SDL_RenderSetScale(). This is because GL_OES_draw_texture  does a unscaled raw blit, ignoring any scaling.

Fix would be to test for the presence of scaling in GLES_RenderCopy() before using the extension.

Bug is present in Android as well as iOS.
