[vulkan] Add support for IQM models Despite the base IQM specification not supporting blend-shapes, I think IQM will become the basis for QF's generic model representation (at least for the more advanced renderers). After my experience with .mu models (KSP) and unity mesh objects (both normal and skinned), and reviewing the IQM spec, it looks like with the addition of support for blend-shapes, IQM is actually pretty good. This is just the preliminary work to get standard IQM models loading in vulkan (seems to work, along with unloading), and they very basics into the renderer (most likely not working: not tested yet). The rest of the renderer seems to be unaffected, though, which is good.

[vulkan] Get IQM rendering working The bones aren't animated yet (and I realized I made the mistake of thinking the bone buffer was per-model when it's really per-instance (I think this mistake is in the rest of QF, too)), skin rendering is a mess, need to default vertex attributes that aren't in the model... Still, it's quite satisfying seeing Mr Fixit on screen again :) I wound up moving the pipeline spec in with the rest of the pipelines as the system isn't really ready for separating them.

[vulkan] Add support for IQM models Despite the base IQM specification not supporting blend-shapes, I think IQM will become the basis for QF's generic model representation (at least for the more advanced renderers). After my experience with .mu models (KSP) and unity mesh objects (both normal and skinned), and reviewing the IQM spec, it looks like with the addition of support for blend-shapes, IQM is actually pretty good. This is just the preliminary work to get standard IQM models loading in vulkan (seems to work, along with unloading), and they very basics into the renderer (most likely not working: not tested yet). The rest of the renderer seems to be unaffected, though, which is good.

[vulkan] Get IQM rendering working The bones aren't animated yet (and I realized I made the mistake of thinking the bone buffer was per-model when it's really per-instance (I think this mistake is in the rest of QF, too)), skin rendering is a mess, need to default vertex attributes that aren't in the model... Still, it's quite satisfying seeing Mr Fixit on screen again :) I wound up moving the pipeline spec in with the rest of the pipelines as the system isn't really ready for separating them.
