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 rectangle in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawRectangle_B_*() functions draws a rectangle with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the functions takes some of the following arguments:
buffer
x
y
w
h
c
c2
a
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
