Writes a pixel of the specified color to a framebuffer at the given coordinates.

void 
put_pixel(
    framebuffer_e framebuffer,
	unsigned int x, 
	unsigned int y, 
	uint32_t color
);

Parameter	Description
framebuffer	The framebuffer to write to. Either BASE or OVERDRAW.
x	Horizontal pixel coordinate. From 0 to ame_state->width - 1 .
y	Vertical pixel coordinate. From 0 to game_state->height - 1 .
color	Pixel color. Format 0xRRGGBB

Return value	none

Edge case	Behavior
x or y is out of bounds	The pixel does not get written and the engine gives a console warning.

Side effect	Description
Pixel write	Alters the contents of the given framebuffer if the coordinates are valid.

Note	Description
Position in the engine pipeline	This function is supposed to be called inside the function game_state->engine_update_framebuffer points to. The changes get rendered after that function ends. See Engine pipeline for the whole pipeline.
