RDP Bugs

[bryanperris]

• Alpha Compare Test: Results are 99% close, some few pixels are off
• Combiner Overflow Test: Some things work and a lot are off
• TextureCoordinates1 Test: Blue color in the lines are missing
• TextureCoordinates2 Test: All colors are missing here
• RDPTex0And1 Test: Some missing green 1s (middle rows), which I blame on alpha bugs but textures themselves look fine
• CombinerLongTailConstants: Only the first RGBW gradient is broken
• RSP DCT Tests (They involve the RDP): The issue with some of them is just related to timing. The test starts the RSP task after waiting for a certain number of RDP commands to be completed.
