repro for the problem

SDL_RenderSetClipRect() works on SDL 2.0.3 but in the current development branch the clipping rectangle is flipped in the Y direction for iOS and Android targets.

Bug 2700 describes a similar problem, but I've reported this when rendering to the device not a texture. It affects iOS and Android and probably other GLES targets.

Attached a repro. The red rectangle should be at the top of the screen, but is instead at the bottom due to the flipped clipping rectangle.

Also attached a patch which fixes the problem for GLES2 renderer, but a glance at the GLES1 renderer, looks like it contains the same code and is presumably similarly broken. I'm not certain my fix is correct but it works in my test case and app.

The same code is also used for the opengl renderer, not only the gles renderers.

I believe this fixes it, which I just pushed for Bug # 2700:

...I think it's identical code to your solution, but if you want to sanity check with the latest in Mercurial, I'd appreciate it. If it's still broken, please reopen this bug!

I checked the released version of 2.0.4 and it is working fine (in my app anyway). Thanks!
