Convert all consecutive calls to d7_DrawPrimitive(TRIANGLE_FAN) into a single call to d7_DrawPrimitive(TRIANGLE_LIST) with all the vertices.
Note, it *increase* the number of vertices, but bandwith is much less costly than multiple calls.
Note, only a very precise subset of the calls get buffered in order to ensure that the disruption is minimal.

-- v21: ddraw: Increasing the vertex batch size on demand ddraw: add d3d_perf statistics on buffering wined3d: Add a TRACE in wined3d_streaming_buffer_unmap() ddraw: Add a local buffer in d3d_device7_DrawPrimitive()
From: Steve Schnepp steve.schnepp@pwkf.org
Convert all consecutive calls to d7_DrawPrimitive() into a single call to wined3d.
The buffer is flushed upon every state change. It is also flushed when incompatible arguments are passed to d7_DrawPrimitive(), such as a changing fvf or incompatible primitive_type.
Note, the call does *increase* the number of data to transmit. This is not an issue because bandwith overhead is much less costly than multiple calls overhead. It will also leverage directly wined3d primitives and allocates space directly in the wined3d device buffer.
Finally, only a subset of the calls get buffered in order to ensure that the disruption is minimal.

Several remarks :
1. I finally squashed everything in 1 commit as it was too cumbersome to maintain the separation. I can split it at the end once everything else is fine.
2. I didn't change (yet) the ddraw_perf channel to d3d_perf as d3d_perf isn't used at all in ddraw.dll.
3. I used HRESULT as a return value for buffer_add instead of bool. I do not like returning bool when it is not obvious what true/false mean. Yet, I don't mind changing it to an enum if one prefers. And of course, I can change it to bool if one insists ;-) --- dlls/ddraw/ddraw_private.h | 37 +++++++ dlls/ddraw/device.c | 216 ++++++++++++++++++++++++++++++++++++- dlls/ddraw/surface.c | 18 ++++ 3 files changed, 268 insertions(+), 3 deletions(-)

This merge request was closed by Steve Schnepp.
I'm closing this PR as I ended up implemented it in userspace at https://github.com/steveschnepp/d3d7batch
Note that the userspace version works also nicely in Windows, and enhance the performance there also, as newer drivers are less permissive.
