We are running Cobalt on a MIPS based platform with no OpenGL support. We have Cobalt from 20.lts.x and it runs perfectly. Now I m experimenting with Cobalt 23 version and I see that OpenGL is the only way to make graphics (we were using Blitter API with 20 version which was removed).
How difficult will it be to port-back blitter API?
As Cobalt is just perfect for constrained systems (embedded systems), what will be your advice for platforms lacking OpenGL support?
You might want to consider a software based OpenGL ES renderer, such as LLVMpipe or OpenSWR. Of course, the rendering performance will likely not be great.
