  Fixed bug 2354 - [ES 2.0] SDL_RenderClear clears render target with wrong color
  
  ny00
  
  SDL_RenderClear clears a render target with the wrong color, if the opengles2 renderer driver is used and the target texture's format is SDL_PIXELFORMAT_ARGB8888.
  
  The bug is *not* reproduced if SDL_PIXELFORMAT_ABGR8888 is used as the texture format (the first from the renderer's list).
  It is further not reproduced using any of the following renderer drivers: opengl, opengles (apparently powered by Gallium3D), software.
  Finally, the correct color can be drawn using SDL_RenderFillRect (instead of SDL_RenderClear).
  
  A few details about the current setup:
  - OS: Ubuntu 12.04 for x86_64
  - GPU: GeForce GTX 460
  - GPU driver version: 331.20-0ubuntu1~xedgers~precise1 (from the xorg-edgers PPA)

  Sam,
  
  It appears that the clear just needs to take the render target format into consideration.
