fix POSITION format (ImDrawVert::pos is 2D, not 4D) ...

the inputlayout incorrectly described the POSITION attribute as being
4D, while ImDrawVert::pos is 2D. This went unnoticed because the buffer
binding has a stride of sizeof(ImDrawVert) and the POSITION is treated
as a float2 in the vertex shader. If you switch POSITION to float4 in
the vertex shader (and actually use the z/w in the matrix
multiplication) then everything become wacky-looking since it's
interpreting the texture coordinates as z/w. On a similar note: It's
weird that the projection matrix takes z and w into consideration when
those don't exist in the shader due to positions being float2s.

Added example for the Marmalade platform

Previous SDL implementation didn't work with my OpenGL 3.3 project, spliced the GLFW OpenGL examples on top of the SDL example to create an option that works for me. Could be useful for others.
