- // In OCCT (in version 6.5.2), things about the background drawing
- // are not straightforward and not clearly understandable:
- // - Horizontal gradient is drawn vertically (!), well ok, from top side to bottom one.
- // - Vertical gradient is drawn horizontally (!), from right side to left one (!!!).
- // - First and second diagonal gradients are confused.
- // - Image texture, once set, can not be removed (!).
- // - Texture image fill mode Aspect_FM_NONE is not taken into account (and means the same
- // as Aspect_FM_CENTERED).
- // - The only way to cancel gradient background (and get back to single colored) is to
- // set gradient background style to Aspect_GFM_NONE while passing two colors is also needed
- // (see V3d_View::SetBgGradientColors() function).
- // - Also, it is impossible to draw texture image above the gradiented background (only above
- // single-colored).
- // In OCCT 6.5.3 all above mentioned problems are fixed; so, above comment should be removed as soon
- // as SALOME is migrated to OCCT 6.5.3. The same concerns #ifdef statements in the below code
