Haiku Gets Addon Based OpenGL

Jerome "Korli" Duval has adapted Haiku's MESA-based OpenGL subsystem to an addon format, allowing renderers to be plugged in, with the first one being a MESA software renderer. This system will allow hardware 3D renderering drivers, such as Rudolf's one when adapted, to plug in without requiring specialised libGL.so's for every card. This extends the common BeOS concept of modularity even further, and is somewhat similar to how Be's OpenGL beta worked - each graphics card acquired a third, .3da driver, to add to the kernel and .accelerant drivers.
