Bugs in graphic functions

[wangchong01]

Hello,
I found a bug when I was using the BILT_P function.
When you are using the function like this:

Code:

DIMGROB_P(G1,320,1000);
BLIT_P(G0,0,0,320,240,G1,-100000,0,-100000+320,241);
FREEZE;

Your screen will be in a mess.I think The BLIT_P function will copy the memory in front of the GROB if you copying the GROB with zooming and x(or y) below zero.
When you are using DIMGROB_P in this way:

Code:

DIMGROB_P(G1,320,1000,#FF000000h);

The content of the GROB will also display part of the calculator's memory.
