read 16bit value and convert to 24bit RGB

Calculates frustrum planes in world space

Builds per vertex tangent and bitangents by first finding tangeents and bitangents per face. Then taking the average value at each vertex and then ren

False is fully outside, true if inside or intersects based on iquilez method

Goes through the list of every event that has occurred since the last call of this function and either performs and exit or sends the result to the ev

Runs main application loop

Closing in opposite order to avoid dangling pointers

Sets the internal pointers to the screen and the current scene and inits the software renderer instance.

Starts up subsystems in an order that satifies their dependencies. If at any point any of the subsystem fails to initialize, the success flag is raise

build a table that decodes both magnitude and value of small ACs in one go.

decode image to YCbCr format

@OPTIMIZE: store non-zigzagged during the decode passes, and only de-zigzag when dequantizing

returns 1 if "a*b + add" has no negative terms/factors and doesn't overflow
