Modify framebuffer and NGA framebuffer to read screen size from board model dtb file. Optimise memory usuage of frame buffer
Add example minigui application with hooks to profiler (which writes results to S:\). Modified NGA framebuffer to run its own dfc queue at high priority

\fBSDL_Cursor *\fBSDL_CreateCursor\fP\fR(\fBUint8 *data, Uint8 *mask, int w, int h, int hot_x, int hot_y\fR);
.SH "DESCRIPTION"
.PP
Create a cursor using the specified \fBdata\fR and \fBmask\fR (in MSB format)\&. The cursor width must be a multiple of 8 bits\&.
.PP
The cursor is created in black and white according to the following:

\fBData / Mask\fR
\fBResulting pixel on screen\fR
.TP 20
0 / 1
White

1 / 1
Black
.TP 20
0 / 0
Transparent
.TP 20
