        TM Verification Order:  1) tm_load.v
                                2) TMEM.v
                                3) tm_mux.v


Test Cases:

tm_load.v

	- load all 10 texel type/sizes into 4K TMEM. this will partly verify
	  tc_sort and verify tm_load.

TMEM.v

	- read entire TMEM out over copy_bus as 16-bit RGBA. this will verify
	  that the TMEM was actually loaded correctly.

tm_mux.v

	- read entire TMEM out by reading all 18 tiles. this will further
	  verify tc_sort and verify tm_mux.
