- Removed the 'fb_width_from_pitch' variable and replaced its usage with 'sys_framebuffer_pidth' to standardize the handling of framebuffer width-from-pitch across the codebase. - Updated references to 'fb_width_from_pitch' in display and screen update functions to use 'sys_framebuffer_pidth', ensuring consistent calculations. - Replaced 'sys_framebuffer_pitch / (sys_framebuffer_bpp / 8)' with 'sys_framebuffer_pidth' to avoid redundant calculations and improve code readability. - Fixed framebuffer calculations in 'GrCalcScreenUpdates', 'GrUpdateScreen32', and related functions to use the correct framebuffer width-from-pitch value. - Corrected and simplified screen update logic in 'GrZoomInScreen' and 'GrUpdateScreen'.
