()[model-view]: Delete field. [model, view]: New fields. * sly/render/camera.scm (with-camera): Use separate model/view matrices. * sly/render/shader.scm (%default-shader): Specify model, view, and projection uniforms. * sly/render/sprite-batch.scm (sprite-batch-flush!): Use new model, view, and projection uniforms. * data/shaders/default-vertex.glsl (model, view, projection): New uniforms.
