DESCRIPTION
Each of the mlib_GraphicsDrawRectangle_*() functions draws a rectangle
with the upper-left corner at (x, y), width w, and height h.
Each of the mlib_GraphicsDrawRectangle_X_*() functions draws a rectan‐
gle in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawRectangle_B_*() functions draws a rectan‐
gle with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
PARAMETERS
Each of the functions takes some of the following arguments:
buffer Pointer to the image into which the function is drawing.
x X coordinate of the upper-left corner of the rectangle.
y Y coordinate of the upper-left corner of the rectangle.
w Width of the rectangle.
h Height of the rectangle.
c Color used in the drawing.
c2 Alternation color.
a Alpha value for blending. 0 ≤ a ≤ 255.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
