4Subject: [PATCH 4/8] ARM: NEON: Bilinear macro template for instruction scheduling
5
6This macro template takes 6 code blocks.
7
81. process_last_pixel
92. process_two_pixels
103. process_four_pixels
114. process_pixblock_head
125. process_pixblock_tail
136. process_pixblock_tail_head
14
15process_last_pixel does not need to update horizontal weight. This
16is done by the template. two and four code block should update
17horizontal weight inside of them. head/tail/tail_head blocks
18consist unrolled core loop. You can apply instruction scheduling
19to the tail_head blocks.
20
21You can also specify size of the pixel block. Supported size is 4
22and 8. If you want to use mask, give BILINEAR_FLAG_USE_MASK flags
23to the template, then you can use register MASK. When using d8~d15
24registers, give BILINEAR_FLAG_USE_ALL_NEON_REGS to make sure
25registers are properly saved on the stack and later restored.

4Subject: [PATCH 5/8] ARM: NEON: Replace old bilinear scanline generator with new template
5
6Bilinear scanline functions in pixman-arm-neon-asm-bilinear.S can
7be replaced with new template just by wrapping existing macros.

4Subject: [PATCH 8/8] Generic C implementation of pixman_blt with overlapping support
5
6Uses memcpy/memmove functions to copy pixels, can handle the
7case when both source and destination areas are in the same
8image (this is useful for scrolling).
9
10It is assumed that copying direction is only important when
11using the same image for both source and destination (and
12src_stride == dst_stride). Copying direction is undefined
13for the images with different source and destination stride
14which happen to be in the overlapped areas (but this is an
15unrealistic case anyway).
