SRGB Block
The sRGB block performs two primary functions:
The function is applied to the entire window by programming the window control to full screen.
Each color channel acts independently. Simple digital contrast and brightness are programmable
with this hardware function. The desired window coordinates are programmed into the TCON.
The 8 corners of the color cube are independently controlled in 3D space with smooth interpolation
of intermediate colors. Registers are 2’s complement color delta’s. For example, to make WHITE
more like RED, program SRGB_WHITE_R to a small positive value.
