void glVScroll(int left, int top, int cols,
void glXPutBitmap(int left, int top, int width,
Scrolls up or down, within the defined window by x number of pixels. The opposite edge of the scrolled
window will be filled in with white pixels. The window must be byte-aligned.
Parameters will be verified for the following:
left is the top left corner of bitmap, must be evenly divisible by 8.
top is the top left corner of the bitmap.
cols is the number of columns in the window, must be evenly divisible by 8.
rows is the number of rows in the window.
nPix is the number of pixels to scroll within the defined window (a negative value will produce a scroll
up).
None.
Draws bitmap in the specified space. The data for the bitmap are stored in xmem. This function calls
glXPutFastmap automatically if the bitmap is byte-aligned (the left edge and the width are each
evenly divisible by 8).
Any portion of a bitmap image or character that is outside the LCD display area will be clipped.
left is the top left corner of the bitmap.
top is the top left corner of the bitmap.
width is the width of the bitmap.
height is the height of the bitmap.
bitmap is the address of the bitmap in xmem.
None.
