This morning I worked on the OpenGLESv2 side of things, writing code to make LDP-1450 text overlay run fast on the Raspberry Pi. I am basically caching every character that can be displayed as a texture and then when I render it, each rendered character will be a rectangle with a portion of the texture applied. It should be pretty fast. If it's not... *ominous music*
Unfortunately, anything to do with GLES2 is quite difficult to get working right. So this could take me a while. I've been dreading it but I finally forced myself to do it so the train is moving.
