The x and y coordinates are derived properly from clip and dest rect with this fix.
- Even if rotation is involved, we need to start reading from the same point.
- Do scaling operation on the delta, and then add the source left and top values.
- If we scale the result of addition, we will not be reading source correctly.

Assign the correct blending value
for MDP 3.0, earlier it was
incorrectly assigned to zero
for cases where blending was not needed.

Add the following optimizations for the temporary buffer:
- Initialize the temp buffer only when required.
- The temp buffer is not deallocated/released unless there is a
change in size of the temporary buffer.

Android YUV formats are aligned to 16pixels, while C2D requires 32pixel
aligned. Use a temp buffer to do the conversion.

Add support to set the framebuffer width and height in the copybit
context. This parameter will be set for composition using c2d where
the c2d target is calculated based on the framebuffer width and height.

Add the copybit header file in the libcopybit directory. Modify the
copybit source files to read from the correct header file.

The patch sets the status as COPYBIT_FAILURE in case of an error in
open_copybit() as it needs to return the correct status. It also sets
the copybit device handle as NULL.

Set the premultiplied format for the source and destination formats if
COPYBIT_PREMULTIPLIED_ALPHA has been enabled

When performing the copybit blit operation, do a blind blit of the
surfaces. The blending operation should be done when the stretch operation
is invoked.
Add the exported sanitized kernel headers to include path in C2D/
copybit, gralloc and overlay HAL libraries.

Gralloc buffers which have the PRIV_FLAGS_USES_PMEM_ADSP
flag are allocated from a pmem region.
Set the kgsl memory type to PMEM to reflect this change.

up until now we relied on the EBI region map_offset being zero, which
prevented us to use SMI for surfaces, as their map_offset is different.
the copybit hal needs the map_offset to figure out which region to use.

add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger
also make sure to not send empty rectangles to the MDP.
The kernel will only do it for images with an alpha plane.
