 As one example, consider rendering a shadow map that will be accessed when shading a g-buffer.
 Depending on the geometry that was rendered into the g-buffer, and the occlusion that might exist, some parts of the shadow map might not be needed at all.
 
-In principle, an application could use a compute pass on the g-buffer to compute, for each pixel, the part of the shadow-map textuer that it will access - its footprint.
+In principle, an application could use a compute pass on the g-buffer to compute, for each pixel, the part of the shadow-map texture that it will access - its footprint.
 The application could then aggregate these footprints into a stencil mask or other data structure that could be used to optimize the rendering pass that generates the shadow map.
 
 Unfortunately, it is almost impossible for applications to accurately and reliably predict the texel data that particular sampling operations will require, once non-trivial texture filtering modes are considered.
