To do the conversion, a specific matrix must be used for each color range (DRM_COLOR_*_RANGE) and encoding (DRM_COLOR_*). This matrix is stored in the `conversion_matrix` struct, along with the specific y_offset needed. This matrix is queried only once, in `vkms_plane_atomic_update` and stored in a `vkms_plane_state`. Those conversion matrices of each encoding and range were obtained by rounding the values of the original conversion matrices multiplied by 2^32. This is done to avoid the use of floating point operations. The same reading function is used for YUV and YVU formats. As the only difference between those two category of formats is the order of field, a simple swap in conversion matrix columns allows using the same function.
