| 187 | * LookupID*(dbe_back_buffer_id) to return the window structure that the
|
|---|
| 188 | * id is a back buffer for. Since both front and back buffers will
|
|---|
| 189 | * return the same structure, you need to be able to distinguish
|
|---|
| 190 | * somewhere what kind of buffer (front/back) was being asked for, so
|
|---|
| 191 | * that ddx can render to the right place. That's the problem that the
|
|---|
| 192 | * following code solves. Note: we couldn't embed this in the LookupID*
|
|---|
| 193 | * functions because the VALIDATE_DRAWABLE_AND_GC macro often circumvents
|
|---|
| 194 | * those functions by checking a one-element cache. That's why we're
|
|---|
| 195 | * mucking with VALIDATE_DRAWABLE_AND_GC.
|
|---|
| 196 | *
|
|---|
| 197 | * If you put -DNEED_DBE_BUF_BITS into PervasiveDBEDefines, the window
|
|---|
| 198 | * structure will have two additional bits defined, srcBuffer and
|
|---|
| 199 | * dstBuffer, and their values will be maintained via the macros
|
|---|
| 200 | * SET_DBE_DSTBUF and SET_DBE_SRCBUF (below). If you also
|
|---|
| 201 | * put -DNEED_DBE_BUF_VALIDATE into PervasiveDBEDefines, the function
|
|---|
| 202 | * DbeValidateBuffer will be called any time the bits change to give you
|
|---|
| 203 | * a chance to do some setup. See the DBE code for more details on this
|
|---|
| 204 | * function. We put in these levels of conditionality so that you can do
|
|---|
| 205 | * just what you need to do, and no more. If neither of these defines
|
|---|
| 206 | * are used, the bits won't be there, and VALIDATE_DRAWABLE_AND_GC will
|
|---|
| 207 | * be unchanged. dpw
