Jelle Raaijmakers 8c9fa50c61 LibSoftGPU: Apply regular cartesian coordinate system ... Currently, LibSoftGPU is still OpenGL-minded in that it uses a coordinate system with the origin of `(0, 0)` at the lower-left of textures, buffers and window coordinates. Because we are blitting to a `Gfx::Bitmap` that has the origin at the top-left, we need to flip the Y-coordinates somewhere in the rasterization logic. We used to do this during conversion of NDC-coordinates to window coordinates. This resulted in some incorrect behavior when rasterization did not pass through the vertex transformation logic, e.g. when calling `glDrawPixels`. This changes the coordinate system to OpenGL's throughout, only to blit the final color buffer upside down to the target bitmap. This fixes drawing to the depth buffer directly resulting in upside down images.		2022-02-22 23:48:59 +00:00
